android系统暗码启动应用

1.创建广播接收器MemoryReceiver

  public class MemoryReceiver extends BroadcastReceiver {

    public static final String MY_SECRET_CODE = "1313";

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        Log.d("MemoryReceiver" , "action==>"+action);
        if ("android.provider.Telephony.SECRET_CODE".equals(action)){
            String host = intent.getData() == null ? null : intent.getData().getHost();
            if (MY_SECRET_CODE.equals(host)){
                //这是启动一个activity
                Intent target = new Intent();
                target.setClassName(context.getPackageName(), context.getPackageName()+".development.memory.SetMemoryActivity");
                target.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                try {
                    context.startActivity(target);
                } catch (Exception e){
                    Log.d("MemoryReceiver" , ""+e);
                    e.printStackTrace();
                }
            }
        }
    }
}

2.注册这个广播
AndroidManifest.xml

<receiver android:name="com.android.settings.development.memory.MemoryReceiver">
      <intent-filter>
          <action android:name="android.provider.Telephony.SECRET_CODE" />
          <data android:scheme="android_secret_code" android:host="1313" />
      </intent-filter>
</receiver>
