Why an activity doesn't start?

Question

I call an aidl method that calls me back after some logic, in this callback method I try to start an Activity, but the activity doesn't start and there are no exceptions. Interesting fact, it works on Android 9, but on 10 and 6 doesn't.

Manifest

<activity
            android:name=".views.ReceiptsActivity"
            android:launchMode="singleInstance"
            android:windowSoftInputMode="stateHidden|adjustPan">
            <intent-filter>
                <action android:name="com.bifit.cashdesk.mobile.views.ReceiptsActivity" />
                <category android:name="android.intent.category.DEFAULT"/>
            </intent-filter>
</activity>

StartActivity() Method

    private void showActivity() {
        Intent intent = new Intent(context, context.getClass());
        intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
        context.startActivity(intent);
    }

Aidl callback method

aidlService.cancel(new IOperationResponse.Stub() {
                @Override
                public void onResponse(String resultCode, String responseData, String rrn, String billJson) {
                    showActivity();
                }
            }, "com.bifit.cashdesk.mobile.views.ReceiptsActivity", rrn);

I have tried to resolve this by user-permissions, but it haven't led to success

 <uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
 <uses-permission android:name="android.permission.READ_PHONE_STATE" />

Answer 1

It was on the side of aidl app, this app didn't close when used callback. We resolved it by closing aidl app on callback on it's side
