无法从Android Oreo中的服务启动startActivity

Question

My App Crash due to start activity from service.

Is there any way to startActivity from service in Android Api 26(oreo) version i am using below code to start activity*

Intent stopDialog=new Intent(this, DialogActivity.class);
        stopDialog.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
        stopDialog.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(stopDialog);

Answer 1

Make sure your Activity is mentioned in AndroidMenifest.xml file. If this is mentioned then try this:

Intent stopDialog = new Intent();
stopDialog.setClass(this, DialogActivity.class);
stopDialog.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(stopDialog);

Answer 2

finally i have solved my problem myself i was using orientation in activity which is starting from service and logcat says me you can use orientation only in fullscreen activity

Here is solution i have removed orientation tag from activity

 <activity
            android:name=".DialogActivity"
            android:excludeFromRecents="true"
            android:launchMode="singleTop"
            android:theme="@style/MyDialogTheme">
        </activity>
