There are some external stereo microphones for IOS that plug into the headphone jack rather than the dock connector. For instance, the IK Multimedia iRig MIC Cast.
They claim that they work on Android as well.
Well, they may work, but do they provide better sound quality than the internal phone microphone, turning it into a decent digital recorder for music, for example? (with the right software, of course).
My question isn't really whether those microphones are better quality than the internal microphones, as I assume they are. But does the headphone jack on Android phones (mine is the Galaxy S4) really provide the input capability for better quality sound, including in stereo?
Of course that jack can transfer sound in both directions, headset and microphone, as it is a phone. For output, the phone provides quality stereo music output to headphones, as modern phones are also music players. However, the microphones on phone stereo headsets are generally low quality monaural microphones only suitable for phone calls, usually not better than the internal microphone, might be worse.
So the question is--is the input function of that jack capable of providing quality stereo input, if one has a quality stereo microphone attached? (No matter how good quality the microphone is, if that jack really cannot transmit that quality sound, but reduces it to a very low resolution and frequency-reduced monaural sound, no point at all in attaching such a microphone.
input capabilities of the headphone jacks on Android phones. (If it varies from phone to phone, then how about mine, the Galaxy S4?)
I don't own an Epic but have thought about jumping from verizon to sprint for their superior 3G coverage in my area. The only phone that interests me is the Epic so I have been reading a lot of forums and reviews. I have heard that the Samsung is supposed to have great quality through the 3.5mm(I think because of some pre-amp or dedicated part of the processor. I'm no expert and cant remember what I read and where).
I haven't really seen to many comments about the audio quality from the 3.5mm headset jack and also the exterior speaker loudness and quality. Coming from the Original Moto Droid it has the best external speaker on any other phone I've owned thus far but sub-par 3.5mm headset jack quality/loudness. Can anybody give me some of their personal opinions on how they think the Epic external speaker matches up to the original Moto Droid and how about the quality/loudness out of the 3.5mm.
I really liked being able to plug my Blackberry into my car stereo and have a really cheap hands free solution. When I plug my Hero into my stereo the microphone becomes muted. Anybody know how to fix this? Is it possible?

Is there anyway to read data from an attachment through the USB port on an Android device? In particular, an EKG. Most the work can be done by the hardware of the device to simplify the output to a single number, a voltage reading. If its not possible, what about modifying an accessory that can already communicate with an android device? Thinking of devices that attach to android phones, what about sending the data as an audio signal to be read as the microphone from a headset and then analyzing the audio signal to convert it to a number that can be used to display a value. how to make this work?

View 5 Replies View RelatedI've noticed lately that some app recommender programs seem to get data off the android market. I'm wondering how I could retrieve information, such as screen shots, description, developer, number of downloads, rating, etc...
I've done many searches and I haven't found any solutions. It would be nice to be able to use that info to be able to see a rating for an app inside an app chooser, for example. Or perhaps be able to track changes and rating over time and version history, etc...
Is there an API to access that information? Is there a way to parse the data from a website? Or is there a complicated hack involved?

I m using Android 1.5 my data directory does'nt have the read/write permissions
System.out.println("DAta can write??--->"+Environment.getDataDirectory().canWrite());
System.out.println("DAta can read??--->"+Environment.getDataDirectory().canRead());
So please suggest me how to provide permission for the data directory.
What m trying to do is to create a file and add some content to it iin the Data storage of the emulator like as below
private void writeToSDCard() {
try {
File lroot = Environment.getDataDirectory();
if (lroot.canWrite()){
File lfile = new File(lroot, "samplefile.txt");
FileWriter lfilewriter = new FileWriter(lfile);
BufferedWriter lout = new BufferedWriter(lfilewriter);
lout.write("XXXXXXXXXXXXXXXXXX");
lout.close();
}
} catch (IOException e) {
Log.e(m_cTAG, "Could not write file " + e.getMessage());
}
}
Is there a way to do it within an app without downloading the file first? Somehow stream the text content?

View 2 Replies View RelatedI am developing an application that needs to access data on the sd card. When I run on my development device (an odroid with Android 2.1) I have root access and can construct the path using:
CODE:..........................
However, when I install this on a phone (2.1) where I do not have root access I get files == null. I assume this is because I do not have the right permissions to read the data from the sd card. I also get files == null when just trying to list files on /sdcard. So the same applies without my constructed path.
Also, this app is not intended to be distributed through the app store and is needs to use data copied separately to the sd card so this is a real use-case. It is too much data to put in res/raw (I have tried, it did not work).
I have also tried adding: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
To the manifest, even though I only want to read the sd card, but it did not help. I have not found a permission type for reading the storage.
