android-intent

问题 My android app is crashing when I try to enable GPS on my android 4.4 (Kitkat) . It's been working fine till Android 4.3 . I am using following code to turn on GPS Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE"); intent.putExtra("enabled", true); this.sendBroadcast(intent); In my Log Cat its giving security exception. My LogCat details are as :- 11-27 12:47:37.410: E/AndroidRuntime(3818): Caused by: java.lang.SecurityException: Permission Denial: not allowed to send

问题 I would like to let user pick directory and save downloaded file (my app downloads file). I know that some tools (for example, ES File Explorer) provide such intent-filters. see http://www.estrongs.com/en/support/developers.html. I start activity for result and then get selected folder as a result. Also, I know that there are no "select folder" intent standards (I can't use the same intent with other tools). Do you know other tools to support such functionality ? I would like to let user use

问题 I have a service I am reusing (it a both a "bound" and "started" service) in my own app because it does a lot of useful data acquisition I'm interested in. Everything was working but I noticed a problem. An exception is thrown in this code: Intent dialogIntent = new Intent(); dialogIntent.setClassName(service.getBaseContext(), "com.mycompany.receiver.ui.DialogActivity"); // names changed to protect the innocent dialogIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE

问题 I have 2 classes. One will be a basic instructions screen and on that screen it will have a menu that will let you go to the other class. The other class is a MapActivity. I believe the problem is that its not finding the other class. I've tried a few different ways of declaring the intent to find the class. This is the latest thing I've tried: @Override public boolean onCreateOptionsMenu(Menu menu){ MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.mainmenu, menu); return

问题 I am trying to make an alarm fire in my app every 30 minutes using Alarm Manager's setExactAndAllowWhileIdle but it is not working! I test the functionality by issuing a push notification whenever I receive an alarm signal. The problem is: when the device enters doze mode after being idle for sometime, I no longer receive alarms. However, as soon as I turn On the screen, I receive a notification. My app needs accurate alarms that need to be delivered exactly on-time every 30 minutes! It can

问题 I'd like one of my activities to pick up a particular url. The pattern is: http://www.example.com/abc123/foo/xyz789 The path components "abc123" and "xyz789" can be any sequence of alpha-numerics, length > 1.
