弹出窗口,即使没有运行应用程序也会发出通知 [英] pop up wiindow with notification even apllication is not running
问题描述
这是我的代码,我可以及时收到通知,但是在弹出窗口时应用程序崩溃了
here is my code and I am getting my notification on time but the application is being ctrash during pop up
private void showCustomPopupMenu()
{
WindowManager windowManager2 = (WindowManager) App.getAppContext().getSystemService(WINDOW_SERVICE);
LayoutInflater layoutInflater=(LayoutInflater)App.getAppContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view=layoutInflater.inflate(R.layout.window_popup_medicine, null);
int LAYOUT_FLAG;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
} else {
LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_PHONE;
}
WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
LAYOUT_FLAG,
WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
params.gravity=Gravity.CENTER|Gravity.CENTER;
params.x=0;
params.y=0;
assert windowManager2 != null;
windowManager2.addView(view, params);
}
并且我得到了类似这样的错误:
and i am getting this kisd of error like :
Unable to add window android.view.ViewRootImpl$W@46b5050 -- permission denied for window type 2038
我已经添加了所有权限:
I have Added all permissions :
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission
android:name="android.permission.INTERNAL_SYSTEM_WINDOW"
tools:ignore="ProtectedPermissions" />
请解决此问题,我将非常感谢您的回答,并在此先感谢您
please resolve this I would really appreciate your answer and thank you in advance
推荐答案
您需要具有ACTION_MANAGE_OVERLAY_PERMISSION权限才能打开/显示警报
You need to have ACTION_MANAGE_OVERLAY_PERMISSION permission to open/display Alert
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
<uses-permission
android:name="android.permission.INTERNAL_SYSTEM_WINDOW"
tools:ignore="ProtectedPermissions" />
将警报类型设置为"TYPE_APPLICATION_OVERLAY".
set alert type of "TYPE_APPLICATION_OVERLAY".
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY);
}else{
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
}
用TYPE_SYSTEM_ALERT

现在,通知到达时,请检查以下内容:
Now when notification arrived, check this:
public void notificationArrived(String myMsg){
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
final boolean overlayEnabled = Settings.canDrawOverlays(MyFirebaseMessagingService.this);
Global.printLog("showTaskDetailPopup==", "overlayEnabled" + overlayEnabled);
if (!overlayEnabled) return;
}
new Handler(Looper.getMainLooper()).post(new Runnable() {
public void run() {
final Dialog dialog = new Dialog(MyFirebaseMessagingService.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.window_popup_medicine);
dialog.setCancelable(true);
TextView tv_msg = dialog.findViewById(R.id.tv_msg);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY);
} else {
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
}
dialog.show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
});
}
