Detect If Camera Is Launched?

Jan 29, 2013

I'm creating an app that launches the video camera using the following code...

[HIGH] Intent intent = new Intent("");
startActivityForResult(intent, 1);[/HIGH]

I only want to launch this if the video camera is not open. I've run into the issue of having multiple video camera screens open.

General :: App That Run Shortcut (activity) When Launched

Jul 21, 2012

Various parts of the Android system or Android apps are designed to launch a program, but aren't capable of launching an application shortcut. For example, they're willing to run a timer application, but they aren't willing to run its "start timer now" shortcut. One example is the samsung ICS lock screen, which is neat in other respects but suffers from this really lame limitation.

Is there an app that can be configured to run another app's shortcut? For example, I could configure the lock screen to launch "Fast Shortcut Helper", and fast shortcut helper will have already been configured to run the "start timer now" shortcut.

Android :: Application Forces Close When Launched From The Market

Jul 2, 2009

I have uploaded application to market and met weird problem which I never received before - when I click "Open" button when the application is installed I receive error dialog and the application is forced to close. I do not have this problem when start application from desktop launcher panel. I have already receive 2 stars for that though the exception even comes not from my cod - very unpleasant surprize from market app.

Application uses vibration and declares corresponding uses-permission "android.permission.VIBRATE" - this is what the exception tells me about, but I can't see such problem with other apps that use vibration on market.

Here the exception:

Android :: Determine If A Specific Activity In An Application Can Be Launched

Jun 9, 2010

Applications can have any number of launchable activities. I know how to get the list of these activities via PackageManager.

Is there a way to determine which activities can be launched via startActivity?

For example, the Documents To Go app has different activities that will start Word, Excel, Powerpoint, PDF, etc... I am able to launch all o these just fine.

However, it also contains some activities that I am not able to launch with startActivity... If I attempt to do this I get a SecurityException.

I want to be able to determine which activities I can safely launch and which I cannot so I only present the user with a list of activities that I can safely launch from within my application...

Android :: Task Activity Stack Always Reset When Launched From Home

Mar 24, 2009

I am just starting on an Android app and I am puzzled about why my Task activity stack is being reset any time the application is launched from the Home screen. I used the ADT tools to create the application in Eclipse. The main activity is ".UserLaunch" and it starts the activity ".About" when the user presses a button. If the user then presses HOME and then relaunches the app, .UserLaunch is displayed and is the only thing on the stack.

.UserLaunch has the launchMode singleTask. .About is standard. According to the documentation at "However, a "singleTask" activity may or may not have other activities above it in the stack. If it does, it is not in position to handle the intent, and the intent is dropped. (Even though the intent is dropped, its arrival would have caused the task to come to the foreground, where it would remain.) "The Task stack should be brought to the foreground and .About should still be displayed. I added Logging to all of the lifecycle events (edited to remove timestamps and shorten DEBUG/ and INFO/ to D/ and I/) and you can see that when HOME is pressed, .About cycles through onPause and onStop (as expected). Then when the app is again launched, .About is destroyed and .UserLaunch is restarted D/UserLaunch:(670): onCreate() D/UserLaunch:(670): onStart() D/UserLaunch:(670): onResume() I/ActivityManager(52): Displayed activity com.cequint.cityid/.UserLaunch: 4910 ms I/ActivityManager(52): Starting activity: Intent { comp= {com.cequint.cityid/com.cequint.cityid.About} } D/UserLaunch:(670): onPause() D/About(670): onCreate() D/About(670): onStart() D/About(670): onResume() I/ActivityManager(52): Displayed activity com.cequint.cityid/.About: 1031 ms D/UserLaunch:(670): onStop() I/ActivityManager(52): Starting activity: Intent { action=android.intent.action.MAIN categories= {android.intent.category.HOME} flags=0x10200000 comp= {} } D/About(670): onPause() D/About(670): onStop() D/dalvikvm(670): GC freed 413 objects / 34128 bytes in 72ms I/ActivityManager(52): Starting activity: Intent { action=android.intent.action.MAIN categories= {android.intent.category.LAUNCHER} flags=0x10200000 comp= {com.cequint.cityid/com.cequint.cityid.UserLaunch} } D/About(670): onDestroy() D/UserLaunch:(670): onRestart() D/UserLaunch:(670): onStart() D/UserLaunch:(670): onResume() Here is the relevant section of the Manifest: <application android:icon="@drawable/icon" android:label="@string/ app_name"> <activity android:name=".UserLaunch" android:label="@string/app_name" android:launchMode="singleTask" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".About" android:launchMode="standard"> </activity> </application> Anyone have any ideas why this is always resetting the Activity Stack?
