Android :: Need To Generate Keystore For Application Public Release?

Oct 19, 2010

After finishing my android application development I used the command showing below to get private key, but it shows some errors such as "The Keystore was tampered with or password was in correct".
$ keytool -genkey -v -keystore DEBUG.keystore
-alias alias_name -keyalg RSA -keysize 2048 -validity 10000
Is my problem with DEBUG.keystore? Should I need to generate another keystore for public release?

Android :: Timeout On Wakelock Causes WakeLock Under-locked Error

Jul 7, 2010

I have a service that acts a download manager, downloading files in the background. I have aquired a partial wake lock while the downloads are going. When the downloads finish, I manually release the wakelock. Because I am paranoid, I acquired the wakelock also with a timeout. The problem I am seeing is that if I have already manually released my wakelock, when the timeout period expires an error is presented to the user (and adb logcat shows an under-locked wakelock exception).

Is there any way to use a timeout (as backup wakelock release in case the app force closes for some reason) without getting this error?

Android :: Wakelock Is Not Turning On Screen?

Sep 11, 2010

I have a signal that puts my app to sleep for a given number of minutes (using AlarmManager) and then wakes it back up.Everything is working except the screen doesn't ever come on.I then release the wakelock when I'm sure that my app is up and running and connected again. However, the screen never comes on! The app only actually comes back to life when I hit the power button to wake up the screen manually.I'm developing on an HTC Hero.

PowerManager And WakeLock - Device Does Not Turn Screen On?

Sep 10, 2010

I'm developing an sms receiver, and i have included a KeyguardManager and a PowerManager to be able to disable the keyguard and turn on the screen if user would like to. This works great, but only once.

When a message is received, the keyguard gets unlocked and the screen is turned on, and it gives out a sound and vibration. But if i don't read the message right away, but let the device power off by screen time out, and i then receive another message while the last one is not read, the device does not turn the screen on again, and it does not give out a sound or vibration, until i turn on the screen manually, then the sound and vibration comes.

If i close all received messages, then my app is able to disable the keyguard and turn on the screen and give out a sound and vibration when a new message is received.Here is my code that is run when the keyguard should be unlocked and the screen should be turned on.

private void disableKeyGuard()
KeyguardManager km = (KeyguardManager)getSystemService(KEYGUARD_SERVICE);
kl = km.newKeyguardLock("SMSHandler");[code].....

General :: AudioMix Wakelock On Stock KitKat?

Dec 6, 2013

I have a N7 2013 on stock KRT16S, and my biggest wake lock is AudioMix.

I'm rooted, using Greenify, and I even have Google Search uninstalled. I am not using GEL. People suggested turning touch sounds off, and I tried that too, but it didn't work.

what is this AudioMix wakelock? Is this like Audio_Out2 on the Nexus 4? Keyboard sounds or any sounds = wakelock? I also find it odd that considering I use my phone on vibrate 98% of the time, that the on my Nexus 4 and older phones, the speaker turns on when I press any button my phone. I thought system sounds wouldn't turn on? Quite interesting. Even in silent mode, the speaker turns on. I know this because my Nexus 4 speaker used to crack everytime it would turn on. To me that's an unnecessary wakelock that should ONLY happen if you're not in silent or vibrate."

General :: Google+ Killing Battery With Partial Wakelock?

Google+ is killing my battery with this partial wakelock. Short of freezing it with Titanium (which does solve the problem for me), how to prevent this from running? It literally runs as long as my phone is on, and is just draining my battery.

General :: Find Exact Process / Service That Is Triggering Wakelock?

Mar 20, 2013

I'm getting beat down with GTALK_ASYNC_CONN wakelocks while on my work's AP.... the specific WL is :gtalk_async_conn something everyone has been complaining about recently, and I never saw it until recently (now that I got up to 4.1.2 a short time ago.

Is there a way to determine exactly who is generating that WL? It's not related to GTALK, as the WL name incorrectly leads us to believe, but it must be google, and I only see it fire when the Wi-Fi is connected and in use. It's non-existent when I'm on Mobile. It comes and goes, sometimes chugging wake time like its cheap beer, othertimes it's dormant, and I haven't been able to figure out who is using it based on the context of when it occurs.

There HAS to be a log or something somewhere that says process X is responsible.

HTC EVO 4G :: 3G Data Cuts Off After 5 Minutes When Screen Off?

Oct 2, 2010

I know this is a rooted issue because it never happened on stock. I have had this problem on Fresh and Baked Snack. Whenever the screen is off and I'm listening to anything that requires mobile data (pandora, streaming radio), it cuts out after about 5 minutes. When I turn the screen on, I can see 3G kick back in and the stream starts again. Is this a known problem with a known solution?

HTC Incredible :: Screen Randomly Turns On Every 5 Or So Minutes

Nov 19, 2010

I just noticed this since the latest update, not sure if it was there or not, and not sure if there is an app that may have recently been updated causing this, but every 5 minutes or so, my screen will flash on for a second or so, and then turn off again. It's rather maddening. Anyone have any idea what might be causing this?

General :: How Does System Generate Settings For Governors

Jul 31, 2013

When I change between governors, I noticed that a governor folder will be created under sys/device/cpu/cpufreq. Within this folder, it contains all the settings and values for this governor. how these settings and values are generated?

I want to modify some settings of the smartassv2. However, if I tried to modify it during the normal, mksh will eat my CPU. I really can't figure out why and this only happens to smartassv2. So I'm looking for an alternative way to modify these settings.

I know nothing about writing applications for Android: What is the simplest way to create an applet that will simply...

1. generate the date and time as "[YYYY-MM-DD] ",
2. copy this string the clipboard
3. display an OK dialog just to confirm that it worked?

Since I know nothing about development on Android and Java, I'd like something that won't take me days to get up and running. Could I get this done in B4A within a day?

General :: Can Have More Than 15 Minutes On Lockout

Jul 16, 2012

I've got an EVO LTE running ICS, Charmeleon rom.

I want to set a PIN lock on the phone so i can enable encryption. but if i do that, the biggest timeout i can set is 15 minutes. I was hoping there was some setting i could tweak somewhere to really increase the maximum timeout. I'd prefer it to be something more like 2 hours, or even a day.

I did see there's an app called delayed lock that'll do this for me, but I want to use the encryption on ICS and it says it wont work with encryption enabled.

Is there someway to increase the lock timeout?

Just to be clear - i'm not talking about the screen turning off - i'm talking about the phone locking and having to enter a pin. Once i boot up the phone I don't want to have to re-enter that PIN again unless the phone has been idle for at least 2 hours (or longer).

General :: Calendar Notification 10 Minutes Before?

Dec 15, 2012

I did a series of upgrades these days (HTC software, googles, updates, etc) and now all my google calendar reminders start 10 minutes before they should. I went to the calendar settings and marked the "default reminder time" as "on time", but whenever I'm creating a new event the reminder is set to 10 minutes before as default...which forces me to change it back to "on time" always.

Android :: IntentService And WakeLock

May 24, 2009

The new IntentService in Android 1.5 looks excellent for handling AlarmManager-initiated broadcasts for scheduled WAKEUP work...except I can't see that it uses a WakeLock anywhere, either in itself or Looper/MessageQueue.

Does this implicitly hold a WakeLock that I'm not seeing? Or would I need to create a WakingIntentService that has an active WakeLock so long as there are messages in the queue?

Android :: WakeLock And KeyGuard

Jun 7, 2010

I'm just wondering if I do this correctly; I'm programming a notification app which can display a notification when the phone is sleeping

Disable keyguard lock. Aquire a wake lock. show notification. Set alarm for timeout and reenabling keyguard and release wakelock is the user dont touches the screen. 4.1 User touches the screen, and I disable the timer. Do nothing more. Done and done 4.2 User dont touch the screen, so reenable keyguard and release wakelock. Phone sleeps again

Basically I'm wondering about point 4.1 the most. cancel the pendingintent for the alarm, and do nothing more? or should the keyguard and wakelock that are set be dealt with in some way?

General :: Data Keeps Cutting Out For 15 Minutes At A Time?

Apr 9, 2014

The oddest thing keeps happening to me. Every now and then, my data just shuts off. It is gone for about ~15 minutes to an hour, then comes back on.

I recently bought a used Galaxy S4, and when I first bought it this happened about every day, then it stopped for awhile, now it just happened again (about 4-5 days since it last happened) so I figured I would try to find out what's going on.

But what's happening isn't making any sense. I have full bars, I have t-mobile on the top, I can make calls, and my data is turned on. It's just not working. Turining data off and on doesn't work, neither does resetting the phone. The only thing that works is waiting. When my data is on, I almost always have fast 4g data, I don't have any issues with connectivity.

I took a screenshot of my Settings screen (with private data removed) for reference. at first the only time this would happen is when I would leave a Wi-Fi connection. I figured the phone just was taking too long to "realize" i wasn't on wi-fi anymore and mobile data needed to turn back on. However, I turned off wi-fi for the last week or so and have been using mobile data exclusively. That's when it started happening less, it's happened about every 3 days since I turned off my wi-fi and about every 1 day before then.

Since a few month my WiFi does not work properly. When I activate it, it automatically connects to the access point. But after 3 minutes, the connection stops working. The WiFi symbol in the status bar disappears and 3g starts working. When i disable and reenable wifi everything works fine again for 3 minutes. I already tried a static IP. Other devices (laptop) have no problems with the same network.
