[Android][AOSP] Run Application in System Process

The method described here is for AOSP make, not including Eclipse and Android Studio build.

In Android.mk, add

LOCAL_CERTIFICATE := platform

In AndroidManifest, under block, add

android:sharedUserId="android.uid.system"

under </application> block, add

android:process="system"

and get back to the project folder and make (command mm) to build the app

To verify, launch the app and check the logcat for log from the app.

If the "Application" column shows "system_process", and the "PID" is the same as other system process (e.g. WindowManager, ActivityManager), then it's successful.

[Android] Debug with Wifi/Bluetooth Instead of USB

It would be much more convenient if we can develop our Android program without the annoying USB line, isn't it ?

Here's how we do it:

1. Connect your PC and your Android phone to the same Local Area Network

  - For WiFi: Connect them to the same AP or make the PC the network sharing server, and vice versa.

 - For Bluetooth: Share the network of the phone with PC via Bluetooth, and vice versa.

2. Connect your PC to your phone with USB line first

3. Open the command line (or simply Win + R) and type:

    adb tcpip 5555

    which means the connecting port is changed to port 5555

4. type:

  ipconfig -all

  which shows all your network connection, and find the IP of the phone.

  (optional) If you've got Apps such as Airdroid which show the IP of your phone, that would even be better.

5. Unplug the USB line

6. type:

  adb connect xxx.xxx.xxx.xxx:5555 (xxx is the IP of the phone)

 and it's done!

 And to undo all these, just simply type

 adb usb

 and the connection will be back to the USB way.

[Android] Hide Input Method Panel

In many cases, we type something in the EditText, and then click the Button, but the Input Method Panel doesn't hide itself. Here's the solution:

Add these lines to your Button function, and the panel will disappear at the moment you click!

InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
if(imm != null) imm.hideSoftInputFromWindow(getWindow().getDecorView().getWindowToken(), 0);

[Android] Keep Service Alive after Screen is Off

Sometimes you just want your background services to keep alive, no matter what happens, even the screen is turned off.
PARTIAL_WAKE_LOCK is just the right thing to do this.


1. Add android.permission.WAKELOCK to your AndroidManifest.xml

2. PowerManager & WakeLock

    claim them as global variable

public class UndeadService extends Service {
  private PowerManager mgr;
  private WakeLock wakeLock;

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
  super.onStartCommand(intent, flags, startId);
  mgr = (PowerManager) getApplicationContext().getSystemService(Context.POWER_SERVICE);
  wakeLock = mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakeLock");
  wakeLock.acquire();               // activate the wakelock
  return START_REDELIVER_INTENT;
}

@Override
public void onDestroy() {
  wakeLock.release();               // release the wakelock
  super.onDestroy();
}
