java – Android阻止用户关闭应用程序

有没有办法我们可以构建自定义MDM,以强制应用程序始终打开.即不要让用户关闭.

我正在构建一个图像库应用程序,以便为用户展示.但我不希望他们能够关闭我的应用程序.

谢谢

有点像这样吗？

public class IntentReceiver extends BroadcastReceiver {
    public static final String TAG = IntentReceiver.class.getSimpleName();


    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i(TAG, "onReceive - intent => " + intent.getAction());

        //Get Intent
        String action = intent.getAction();

        if("android.intent.category.HOME".equals(action)) {

            Intent i = new Intent();
            i.setClass(context, MainActivity.class);
            i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
        }

但是,我还需要知道应用程序何时关闭或被杀？

Let me try to explain better. imagine if an artist wants to display his work via 10 android device. all in the Wall. So he can use this app. I want to lock-down the device. to only run this app and nothing else to work.
Similar conset when you go to a phone shop and all the device is running a demo app and you can’t quit it with out a password. (i.e Apple Store) you can’t quit the app running on these Ipads

解决方法:

我在Android上专门针对Kiosk模式撰写了一篇文章 – 过去只是’任务固定’.

adb shell dpm set-device-owner com.sureshjoshi.android.kioskexample / .AdminReceiver

它有相当多的工作量,但是,一旦你做了样板,你最终会使用这个片段来启用和禁用.

private void enableKioskMode(boolean enabled) {
    try {
        if (enabled) {
            if (mDpm.isLockTaskPermitted(this.getPackageName())) {
                startLockTask();
                mIsKioskEnabled = true;
                mButton.setText(getString(R.string.exit_kiosk_mode));
            } else {
                Toast.makeText(this, getString(R.string.kiosk_not_permitted), Toast.LENGTH_SHORT).show();
            }
        } else {
            stopLockTask();
            mIsKioskEnabled = false;
            mButton.setText(getString(R.string.enter_kiosk_mode));
        }
    } catch (Exception e) {
        // TODO: Log and handle appropriately
    }
}
