I refactored my package name and put my CuteMainActivityin the package org.azurespot.cutemain.CuteMainActivity. Plus rearranged all my other classes. So now I get a red error on the .CuteMainActivity part in my Manifest, where the activity should launch.
I also changed the top package name of my Manifest to the new one: org.azurespot, and also changed my applicationID in my build.gradle file to the new package name org.azurespot too. Then I rebuilt, cleaned, and even tried invalidate and restart to my project but nothing is getting rid of this red error. I also tried to assign the new package/activity name to launch in my run configurations, and got this error:
Launching application: org.azurespot/org.azurespot.cutemain.CuteMainActivity.
DEVICE SHELL COMMAND: am start -n "org.azurespot/org.azurespot.cutemain.CuteMainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=org.azurespot/.cutemain.CuteMainActivity }
Error type 3
Error: Activity class {org.azurespot/org.azurespot.cutemain.CuteMainActivity} does not exist
One strange thing, is that my package name has the word (androidTest) beside it. Would that make things not work? Usually studio creates a regular package name and a package_name (androidTest), but in the refactoring, I only see this (androidTest) one.
I have been researching this problem for a while, but nothing seems to work. Any suggestions? Thank you.

You should change it to one of the followings:
android:name="org.azurespot.cutemain.CuteMainActivity"
or
android:name=".cutemain.CuteMainActivity"
Ah... the package name with (androidTest) was indeed the culprit. All of the above answers should have fixed things, but the final problem was that when I refactored (I have no idea how it happened), all of my new package names got put into my androidTest directory in the src folder, and nothing was in my main of my src folder. So when my app went looking for the main activity, it could not be found. The fix to this was to put the whole java folder back into the main folder (as it was empty for some reason), then restart the app and everything worked again. It was not necessary to delete the androidTest folder, and it seems fine that it's empty.

I had developed app on android studio 3.0.1, but I got a error when I installed the apk to my cellphone.
Cellphone connect mac by usb, click run button
,the apk will installed and run no error. But if I copy the apk in finder (like this)
to cellphone and install it in phone, there will be an error "APK parsing error".
If install apk by "adb install xxx.apk" ，when open the app, it will crash and logcat as follow:

...etc...
I've "xxxxx"'ed out a proprietary name. What do real application class is null and No instant run dex files added to classpath mean? Also I see the reference to "Unable to instantiate activity ComponentInfo" in a lot of similar questions - what does it mean?
The activity it can't find is declared in the manifest as...
<activity android:launchMode="singleTask"
android:label="#string/app_name"
android:windowNoTitle="false"
android:configChanges="orientation"
android:screenOrientation="landscape"
android:name=".RemoteControlActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I can't even hit a breakpoint at the beginning of the Activity, so how do I debug this?
You can disable InstantRun and see if the problem persists.
I am confused about the permissions section for IBM's MobileFirst GMS Push notifications found here. (Section 5)
https://developer.ibm.com/mobilefirstplatform/documentation/getting-started-7-0/notifications/push-notification-native-android-applications/
I have added all of these permissions verbatim, but im getting an error saying i havn't added manifest permissions. Do i need to modify the package names in these permissions?
Is this activity built in?
<activity

When creating a MobileFirst-based Hybrid app with the Android environment, MobileFirst will be creating it based on a template with a set of predefined permissions and activities.
In a native application, you are the one creating it. MobileFirst only supplies you with the SDK and a set of integration instructions.
The activity that you mentioned in the question (taken from the tutorial page) is the activity of the sample application included in the tutorial. In your own app's AndroidManifest.xml you will see your app's name instead of "androidnativepush" (or rather need to create it).
Make sure not to use "androidnativepush" anywhere unless that is your app name.

I'm using latest AdMob (through Google Play Services lib) API as documented here:
https://developers.google.com/mobile-ads-sdk/docs/
Relevant parts of config:
<application...>
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
<activity android:name="com.google.android.gms.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />
layout xml:
<com.google.android.gms.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adSize="SMART_BANNER"
ads:adUnitId="#string/adMobUnitId" />
code:
//onCreate()...
try {
adView = (AdView) activity.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build();
adView.loadAd(adRequest);
} catch (Exception e) {
Log.e("AdManager", "Unable to load ads", e);
}
//onResume()
adview.resume()
Looks like this only happens on some devices and working fine in emulator and real devices I have access to.
According to Google AdMob Ads Developer group new AdMob SDK should work on devices even if it does not have Google Play installed (btw one crash report is from Nexus7 2013 stock). So I assume it is not a problem...
Also as seen from Ad loading code it is in try/catch and looks like this exception happens even before my code gets executed. This is also seen from exception stack trace (no lines with my app package)
Anybody knows what could be the problem? Any help is appreciated!
Looks like problem has solved after updating Google Play Services lib to the latest version.
