我有一个应用程序,在检测到用户位置后,应用程序会显示附近的银行、餐馆等信息。以前一切正常,但是在最近更新我的Moto X Play设备后,应用程序会要求“检测到屏幕叠加”并崩溃。我不知道如何在我的应用程序中包含此权限。以下是我的代码:

我现在不知道该怎么办。这个应用在之前的设备上运行良好,但对于Marshmallow用户来说,这是非常令人沮丧的情况。请帮忙。
这是我添加的内容,但出现了空对象引用错误。
public void permissionToDrawOverlays() {
if (android.os.Build.VERSION.SDK_INT >= 23) { //Android M Or Over
if (!Settings.canDrawOverlays(this)) {
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION, Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, PERM_REQUEST_CODE_DRAW_OVERLAYS);
}
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PERM_REQUEST_CODE_DRAW_OVERLAYS) {
if (android.os.Build.VERSION.SDK_INT >= 23) { //Android M Or Over
if (!Settings.canDrawOverlays(this)) {
// ADD UI FOR USER TO KNOW THAT UI for SYSTEM_ALERT_WINDOW permission was not granted earlier...
}
}
}
}
我已经在onCreate方法和onLocationChanged方法中各调用了一次此方法。
if(mGoogleApiClient != null) mGoogleApiClient.disconnect();

中添加了<uses-permission android:name="android.permission.ACTION_MANAGE_OVERLAY_PERMISSION"/>
吗? - Kishore Jethava
