android恢复出厂设置,关机,重启以及系统升级和充电器连接广播

恢复出厂设置

<uses-permission android:name="android.permission.MASTER_CLEAR" />

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.P) {
    sendBroadcast(new Intent("android.intent.action.MASTER_CLEAR"));
} else {
    Intent intent = new Intent("android.intent.action.FACTORY_RESET");
    intent.setPackage("android");
    sendBroadcast(intent);
}

关机

<uses-permission android:name="android.permission.SHUTDOWN" />

Intent intent = new Intent("android.intent.action.ACTION_REQUEST_SHUTDOWN");
intent.putExtra("android.intent.extra.KEY_CONFIRM", true);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivityForResult(intent,0);

重启

<uses-permission android:name="android.permission.REBOOT" />

Intent intent = new Intent("android.intent.action.REBOOT");
intent.putExtra("nowait",1);
intent.putExtra("interval",1);
intent.putExtra("window",0);
sendBroadcast(intent);

系统升级

<uses-permission android:name="android.permission.ACCESS_CACHE_FILESYSTEM" />
<uses-permission android:name="android.permission.REBOOT" />

File packageFile = new File("/sdcard/update.zip"); 
RecoverySystem.installPackage(getApplicationContext(), packageFile);

升级最后会调用系统的frameworks\base\core\jave\android\os\RecoverySystem.java中的installPackage函数，
可以通过adb shell进入到tmp目录,然后cat recovery.log来查看升级log

注：Android4.4以前把APK放到/system/app目录才有权限; 
Android4.4以后设置android:sharedUserId="android.uid.system" 后使用系统签名
或：
在/cache/recovery/command文件中写入--update_package=/cache/update.zip
然后adb reboot recovery也可以实现升级

充电器连接广播

public class PowerStateReceiver extends BroadcastReceiver {
	private static Context context = null;
	private static PowerToken powerToken = null;
	
	@Override
	public void onReceive(Context mContext, Intent intent) {
		
		context = mContext;
		if(powerToken==null)
			powerToken = new PowerToken();

		if (intent.getAction().equals(Intent.ACTION_POWER_DISCONNECTED)) {
			Toast.makeText(mContext, "ACTION_POWER_DISCONNECTED", Toast.LENGTH_LONG).show();
			powerToken.setPowerConnected(false);

			new Thread(new Runnable() {
				@Override
				public void run() {
					synchronized (powerToken) {
						try {
							powerToken.wait(3000);
						} catch (Exception e) {
							Debug.printf(e.toString(), null);
						}
					}
					
					if(IsPowerConnected()==false) {
						//TODO ACC 断开三秒关机
					}
				}
			}).start();
		}
		else if(intent.getAction().equals(Intent.ACTION_POWER_CONNECTED)) {
			Toast.makeText(mContext, "ACTION_POWER_CONNECTED", Toast.LENGTH_LONG).show();
			powerToken.setPowerConnected(true);
			synchronized (powerToken) {
				powerToken.notifyAll();
			}
		}
	}

	public static boolean IsPowerConnected() {
		if(powerToken==null) return true;
		return powerToken.isPowerConnected();
	}

	private class PowerToken {
		private boolean powerconnected = true;

		public void setPowerConnected(boolean connected) {
			this.powerconnected = connected;
		}

		public boolean isPowerConnected() {
			return (powerconnected == true);
		}
	}
	
	private void shutdown() {
		Intent shutdownIntent = new Intent("android.intent.action.ACTION_REQUEST_SHUTDOWN");
		shutdownIntent.putExtra("android.intent.extra.KEY_CONFIRM", false);
		shutdownIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
		try {//防止APK不在System目录时,无权限导致崩溃
			context.startActivity(shutdownIntent);
		} catch (Exception e) {
			Debug.printf(e.toString(), null);
		}
	}
}
