General :: Disable Android Media Scanner Service?
Jun 9, 2011And if yes, what is the name of the app/service that I have to freeze using Titanium Backuup?
I have a 8 GB SD Card with only about 550 MB free, and the stupid media service creates 500mb worth of thumbnails and cache. It re-creates it each time I delete the cache. I'm currently running MIUI Gingerbread 2.3.4. Back when I was running CyanogenMod 6.xx I used to simply freeze the Gallery app and that used to solve the issue, but I don't see the gallery app listed in Titanium on the MIUI ROM. Freezing the MIUI Gallery app didn't stop the thumbnail cache creation process.
Creating a .nomedia file in the respective folders isn't an option because I need my photographs (I have about 20k worth of family/spouse pics that I always carry around on my phone in addition to wallpapers etc.) to be visible in Quickpic / Fishbowl photo app etc.

does anyone have any ideas why this isnt working and what i can do to fix it?
Android : Possible To Rescan Sd-card With Media Scanner?
Nov 2, 2009I've already been searching forums and google groups to find out how to force Media Scanner to rescan the sd-card for media files, but with no luck. So after 2 days of searching i decided to post a question here.
In my app i need to rename media files, change their extension, or to reveal them by changing back their extension, but the changes take effect only after i run Media Scanner from the dev-tools, or remount the image, or reboot the phone/emulator. I've tried using MediaScannerConnection, and it only works when revealing media files, but not refreshing the gallery / music player thumbnails which is the biggest problem in my app development right now.
I've also tried copying files and deleting the old ones, but that has no effect also. Does anyone have any experience with this?

Sep 17, 2009I push a audio file named "music.aac" into SD card, and then execute "Media Scanner" application or re-start the device. I found that media scanner didn't process ".aac" file, so the "music.aac" file doesn't exist in music player. But Android supports AAC/AAC+/eAAC format.So who know the reason that the ".aac" file doesn't be processed by media scanner.

Jun 22, 2012I am experiencing massive battery drain from *wakelock*/mediaplayer while music playback.
For now, i have tried everything:
- full wipe
- music playback on fresh wiped rom
- formatting sdcard / internal storage
- disabling media server
- debugging with logcat
- ...
Currently, the mediaserver drains more power then any other process, including screen. The phone gets not hot, but warm while only playing music with screen off. That was not happening before, as i listen music daily.
After all, the problem is most likely caused by a corrupt file, but how can i locate this file ? I have 2300 mp3s on my phone, so testing every single one would be a bit complicated...

General :: Media Scanner SDCard CPU Utilization Battery Drain
Nov 26, 2013Often your Media scanner can misbehave and eat lot of CPU, Battery un-wantedly.
I had been digging out how to fix it, and here are my solutions. Perhaps try al of them, it would definitely relieve your cpu and battery usage by large. Solution works on any Android version:
Solution 1. Clear media storage data
Settings > applications > Media Storage > clear data, force stop and reboot.
Solution 2. Remove unwanted media files Navigate to /sdcard/DCIM/.thumbnails and delete all files. Repeat for external sd card. On AOSP roms, Android gallery creates too many of thumbnails that later becomes problematic for media scanner.
Solution 3. Analyze and delete excessive media files Find out what files are causing media scanner to go mad. Use any sdcard analyst (I use ES file manager > menu > Sd card analyst) to determine which directory has lots of files/subdirectories inside it. Any directory having >1000 files/folders is an alarmingly high number. Get rid of them (if you can).
Solution 4. Probe and delete bad/damaged media If you're sure you've tried above solutions and still encountering battery drain, its time to dig deeper with developer tools. Pre-requisite: You must be rooted, and have android developer tools (adb) setup. With ADB tools installed, enter shell and acquire su permissions
Code:
adb shell
su
Then run top (linux task manager) to see which process is eating cpu. You can filter top results
Code:
top -grep media
this would give you a result like
Quote:
130|root@n7000:/ # top | grep media
1905 0 10% S 7 23080K 6168K bg media /system/bin/mediaserver
2808 0 40% S 3 3524K 740K media_rw /system/bin/sdcard
2825 0 9% S 19 255832K 43936K bg u0_a5 android.process.media
%age cpu shows media server is eating cpu and needs to be fixed. Run the following command to determine which file is it currently reading
Code:
lsof | grep media_rw
If the media service is stuck at a directory/file for a long time, you know it's a damaged media file, you should get rid of it.
Once you get rid of such files, Its guaranteed media server would finish scanning soon enough.
Solution 5: Format SD cards If nothing works (or you're too lazy of trying solution 4): Take backup and format Internal, external sd card and copy only selective files/folders that you need. Problems would go away for sure.
Solution 6: Disable Media scanner If your Droid is against you and it just won't tame, its time to disable the media scanner. You can do this from adb shell
Code:
pm disable com.android.providers.media/com.android.providers.media.MediaScannerReceiver All Solutions with full detail: Fix Android Media server scanner SDcard CPU, Battery drain
General :: Media Scanner / Manager Causing CPU Battery Usage / Drainage
Nov 22, 2012Have a brand new HTC One X+ (AT&T). Having an issue where after boot and sometimes all of the sudden during the day, the phone gets hot and battery level drops l like ton of bricks. Using Android Task Manager App and enabling monitor of system processes and selecting realtime monitor, I've traced the problems to "android.process.media". This appears to be something to do with Android scanning the device for media files (audio/video/etc) and creating some sort of database. I also usually see the "Music Enhancer" process which has to do with Beats Audio according to HTC (but I have Beats turned off.)
I've seen old threads of people with same problem and in some cases it had to do with a "corrupted" media file and they had to remove all media files and/or factory reset their device. I just spent an entire weekend customizing this device! Plus, how the heck do you prevent yourself from copying the corrupted file over if it was a corrupted mp3 or something?
I'm pretty sure my issue stems from the fact I used my media manager (Media Monkey) to sync over 2,800 audio files to the device. My collection is of high bitrate quality, about 16GB worth of music. I'm pretty sure this is what it is choking on. What I'm not sure of is if the Media Scan the Android device is performing is just a "normal check" for changes/addition/deletions to any of the media files. This of course would take a lot of time and CPU if it has to scan 2,800 files every reboot or periodically. It seems launching Google Play sometimes starts it too as I also sometimes see Google Play Service:Music or something like that (even though I don't stream any of my audio from Google Play.)
General :: Galaxy Note I717 / ICS 4.0.4. - Media Scanner Making Duplicate Song Entries
Sep 28, 2012I used to have a problem with the media scanner making duplicate song entries, only one would play and the other was invalid. For some reason that went away and now it adds media once and never scans again, so if I add songs later they never get picked up to be shown in the music player or winamp etc.
I found these tips:
go to application manager> all application and search
-media storage,
-music player,
-gallery application
and just delete cache and data and restart. It will solve the problem a it force to re build data base
This works still but it is a complete PITA because it resets wallpapers, ringtones and all sorts of other things to default and I don't want to have to do this every time I add a song. How do I fix the media scanner, does it even have logs or something I can look at?

Samsung Captivate :: Captivate/Android Media Scanner/Playlists ?
Sep 8, 2010I am having an issue with my M3U playlists.
I use the default Samsung media player, Isyncr and Itunes. Although I have also used the Doubletwist Player (not the desktop software) and had the same issue, I just prefer the Samsung default player mainly because of the lock screen app.
Here is the issue.
First, I sync my playlists with Itunes using Isyncr, all of the songs come over great, art and tags, everything is perfect. It also creates M3U playlists on my phone. I double checked that everything is there.
Then when I unmount, media scanner scans my SD card (which takes way longer than it should) and it deletes all of my playlists. Now a little research on XDA forums tells me that this is because anytime the media scanner scans a playlist and can't find all of the songs from that playlist, it assumes it is an old playlist and deletes it. The problem is that when I look through the M3U files, every song referenced in the list is on the card...they are all there, yet it keeps deleting them.
Does anyone know of a solution to make it stop deleting my playlists?

Sep 15, 2010When I create a instance of the SQLiteOpenHelper, I always need a "Context" to be passed as its constructor's argument. To use this "Context", in my service layer class, I extends Activity class, though I do not display this activity on the screen because it is my service layer. I always get NullPointer exception when I open the SQLiteOpenHelper in my service layer class, Is it because my service layer class extends the Activity class but I did not show this activity on mobile screen? (That's there is no intent to my service layer class), if it is so, how to get rid of it if I wanna open a SQLiteOpenHelper in my service layer class which do not need to extends Activity, but need a Context object to pass to SQLiteOpenHelper?

Android :: How To Use Media Player In Library Class?
Feb 25, 2009I have successfully implemented the Media Player for my apps, but when I tried to use some of the callback methods I ran into a problem.What I'm trying to do is use Media Player in a reusable (library) class.This MediaPlayer is created by passing the Activity Context to it's constructor.I then use getApplicationContext to avoid any potential memory leaks.This works well and I'm quite happy with it.My problem is trying to use callbacks.When I implement MediaPlayer.OnPreparedListener in my class.I believe this is due to the class itself not being an Activity.When I implemented the callbacks in a separate test project, the mp.prepare () works fine. I cannot use a passed context to my library class, as that would require the Activity to implement the listener and not my library class. How can I create a library class that creates/uses MediaPlayer and it's callbacks without making it extend Activity?Is this not possible?
View 3 Replies View RelatedAndroid :: Class Derived From Intent Service Must Have Default Constructor
May 8, 2009I'm posting this to share the lessons I learned while working with IntentService. IntentService has a single constructor that takes a string argument "name". The documentation has no description of what name is used for. In looking at the sources, I found that its only use is in naming the worker thread for the IntentService. This thread is named IntentService [name].
I initially implemented the constructor of the derived class to also take a String argument and passed it along to the derived class. This is wrong. This will cause the startService() call to generated a java.lang.InstantiationException in the application containing the service i.e. you don't get the exception in the application calling startService(). A clue to the actual problem is a little further up in the logs:"newInstance failed: no <init>()"
The derived class must have a Default constructor and that constructor must call super() passing a string for the name component of the worker thread name.
public class MyIntentService extends IntentService {
public MyIntentService() { super("MyIntentService");
} @Override
protected void onHandleIntent(Intent intent) {
// Handle events on worker thread here }
Android :: How To Stop Service Method Of Calling Activity Class?
Jul 2, 2010I am trying to call my service class's stopService() method from my activity. But I don't know how to access stopservice method from my activity class. I have the below code but its not working. This is HomeScreen class:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
enablecheck = (CheckBox)findViewById(R.id.enablecheck);
enablecheck.setOnCheckedChangeListener(new OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(enablecheck.isChecked()){
startService(new Intent(HomeScreen.this, AutoService.class));
} else {
stopService(new Intent(HomeScreen.this, AutoService.class));
} } });
}
This is Service Class:
public class AutoService extends Service {
private static final String TAG = "AutoService";
private Timer timer;
private TimerTask task;
@Override
public IBinder onBind(Intent intent) {
return null;
} @Override
public void onCreate() {
Toast.makeText(this, "Auto Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
int delay = 5000; // delay for 5 sec.
int period = 5000; // repeat every sec.
timer = new Timer();
timer.scheduleAtFixedRate(task = new TimerTask(){
public void run() {
System.out.println("done");
} }, delay, period);
}
@Override
public boolean stopService(Intent name) {
// TODO Auto-generated method stub
timer.cancel();
task.cancel();
return super.stopService(name);
} }
Android :: Service Unable To Call Java Class Methods / Way To Fix?
Jun 22, 2010Hi, custom classes which are part of a framework, so nothing graphical. One of those (singleton) classes is a Logging class which send logs to my server. I noticed that even though I can call the classes methods in my service it actually won't be logging anything... In my specific example it's osmething like : Logger.getInstance().log("Whatever I want to Log"); Obviously the getInstance is a static method so it can be accessed from anywhere within my project right away.. I was wondering though why this method for example isn't getting called ? Also how do I debug a Service ? Btw I am using of IPC from one of my Activities which gets bound to the service and can start/stop the music for example...

Android :: Call AsyncTask Methods From Another Class - Service - Callbacks?
Jun 1, 2010I was wondering if it's possible to call specific methods defined within the AsynTask class from another class and/or service ?
In my specific case I have a Service playing some sounds, but the sound is selected from a List with available sounds...
When a sounds is selected it is downloaded from my home server, this takes some time (not much, let's say around the 3-4 seconds, the sounds/effects aren't big in size)...
So my problem at the moment is that I have a service to play those sounds, and when I select one I wanted to show a progressdialog... The way (if I understood correctly) is to use an AsyncTask, but the only thing the AsyncTask will do is telling my Service to play a specific sound from my server... So there is no "callback" from the service to the Asynctask...
How can I call a running AsyncTask, which sits in another class, and tell him all work is done and thus he can stop showing the ProgressDialog ? Or am I over-engineering it and there are other ways ?

Android :: Inside Service Class / Executing Method For Toast From Scheduled TimerTask
Apr 30, 2010I am trying to execute a {public void} method in Service, from scheduled TimerTask which is periodically executing.This TimerTask periodically checks a condition. If it's true, it calls method via {className}.{methodName};However, as Java requires, the method needs to be {pubic static} method, if I want to use {className} with {.dot}.The problem is this method is for notification using Toast(Android pop-up notification) and Status Bar.But for this to work, the method must not have {static} modifier and resides in Service class.So, basically, I want background Service to evaluate condition from scheduled TimerTask, and execute a method in Service class.Can anyone help me what's the right way to use Service, invoking a method when certain condition is satisfied while looping evaluation?

Jun 4, 2010I'm new in Android development and I have the next question/problem. I'm playing around with the Media Recorder class to record just audio from the microphone. I'm following the steps indicated in the official ://developer.android.com/reference/android/media/MediaRecorder.html
So I have a method that initializes and configure the Media Recorder object in order to start recording. Here you have the code:
//initializes audio recorder
//configure the input sources

//set the output format
mrecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
//set the audio encoding

Android :: Media Recorder Class Setting Audio Source / Unsupported Parameter
Jun 9, 2010I'm new in Android development and I have the next question/problem. I'm playing around with the Media Recorder class to record just audio from the microphone. I'm following the steps indicated in the official site:
http://developer.android.com/reference/android/media/MediaRecorder.html
So I have a method that initializes and configure the MediaRecorder object in order to start recording. Here you have the code:
this.mr = new MediaRecorder();
this.mr.setAudioSource(MediaRecorder.AudioSource.MIC);
this.mr.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
this.mr.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
this.mr.setOutputFile(this.path + this.fileName);
try { this.mr.prepare();
} catch (IllegalStateException e) { Log.d("Syso", e.toString());
e.printStackTrace();
} catch (IOException e) { Log.d("Syso", e.toString());
e.printStackTrace();
}
When I execute this code in the simulator, thanks to logcat, I can see that the method setAudioSource(MediaRecorder.AudioSource.MIC) gives the next error (with the tag audio_ipunt) when it is called:
ERROR/audio_input(34): unsupported parameter: x-pvmf/media-input-node/cap-config-interface;valtype=key_specific_value
ERROR/audio_input(34): VerifyAndSetParameter failed
And then when the method prepare() is called, I get the another error again:
ERROR/PVOMXEncNode(34): PVMFOMXEncNode-Audio_AMRNB::DoPrepare(): Got Component OMX.PV.amrencnb handle
If I start to record by calling the method start(). I get lots of messages saying:
AudioFlinger(34):RecordThread: buffer overflow
Then after stop and release, I can see that a file has been created, but it doesn't seem that it been well recorded. Anyway, if I try this in a real device I can record with no problems, but I CAN'T play what I just recorded. I guess that the key is in these errors that I've mentioned before.
