I have an issue with AWS Amplify for Android. I am using Cognito and S3, both configured though Amplify. When I init my app it crashes for API level lower than 21. If I run it with API level 21 or higher, it runs successfully. This is the exception:

I am using guest authentication with Cognito, and S3 with public access to objects. The crash occurs here:
class DidonatoApplication: Application() {
override fun onCreate() {
super.onCreate()
try {
Amplify.addPlugin(AWSCognitoAuthPlugin()) //HERE throws exception
Amplify.addPlugin(AWSS3StoragePlugin())
Amplify.configure(applicationContext)
Log.i("DidonatoMobile", "Initialized Amplify")
} catch (error: AmplifyException) {
Log.e("DidonatoMobile", "Could not initialize Amplify", error)
}
}
}
Any one have an idea what could be the problem?
I had a similar problem, but a different class definition that couldn't be found.
I noticed that my implementations for the various Amplify plugins in the build.gradle file used different versions. Matching the versions fixed the errors (in my case I went with my lowest version - 1.0.0).

I was trying to run an app that requires MultiDex using Android Studio 3.0 on an API 16 device and when the app is finally trying to launch, it crashes.
The same occurs on other low APIs (eg.: 17, 18, 19)
But, when I tried to run the app using the Android Studio 3.1 (beta version), no crashes occur.
Is there any way this crash can be fixed?

Issue should be about enabling "advanced profiling" feature in AS 3.0, if you've done so just disable it:
Go to "Edit Configurations...",
Select your app configuration under "Android App",
Then go "Profiling" tab and
Uncheck "Enable advanced profiling"
Problem should be gone.
I'm building LatinIME source code provided by google-source in android-studio but i got a bug in ProximityInfo.java line 89 which show a dialog and i have added a jni_latinime.so
in src/main/jniLibs

Your screenshot suggests that your jniLibs contains a jar file with prebuilt native library. I did not know that this is even possible, but yes, it works in Android Studio 2.3 and higher. Nice!
Anyways, as I explained elsewhere, don't expect Android Studio to resolve magically the native method declarations into a prebuilt library (even if it is unpacked into src/main/jnLibs).
You can simply ignore this error message: your APK will still install the prebuilt library, and the native method will be resolved at run time.
You can add #SuppressWarnings("JniMissingFunction") annotation for this method, or for the entire class:
#SuppressWarnings("JniMissingFunction")
public class ProximityInfo {
or configure this kind of Lint inspections for the given project, or for all projects:
This is very old query and hopefully must have been solved by now. But still wanted to put my comment on this.
As I can see this is a run time error and related to "UnsatisfiedLinkError", which means that the application is unable to link to the library that it is looking for. Hence the library "latimime" is missing when the application is bundled.
To make sure that the library is bundled along with the application, you can extract the APK and check.
I use version of Android Studio 1.5.1
If I create new project and MainActivity extends AppCompatActivity then it does not work it gives error like:

I create new project. Not change anything only run it.but it gives error.
How can i use AppCompatActivity.
Your logcat throws
This app has been built with an incorrect configuration.
You should use latest gradle plagin version
classpath 'com.android.tools.build:gradle:2.2.2' //2.2.0
Here is Demo
dependencies {
classpath 'com.android.tools.build:gradle:2.2.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
FYI
You can add this in your build.gradle section .
android {
defaultConfig {
vectorDrawables.useSupportLibrary = true
}
}
Then Clean-Rebuild, Sync & Run.
My Xamarin Android app is already in production, people are downloading it from Google play and everything seems to be fine, except from time to time I get following errors in Google Play Developer Console :

I've got zero google results for ClassNotFoundException + mono.android.app.Application. According to Developer console it comes from android 4.2 and 4.4., different devices (HTC, Samsung..), even from devices which i tested and everything works (HTC One).
Any ideas? Is this bug in mono? or Xamarin? Or am I doing something wrong?
Whenever xamarin app install in the device it is find to mono runtime support lib, if it is not installed in the device then it will stop to run so, if u have run without mono installation you can change some settings on:
Property => Android Option
Go to Packaging and select only one Bundle assemblies into native code, and also go to linker and select linking is None then run it.
I hope it might work.
Every time I start my Android instrumentation test it fails with
android.test.suitebuilder.TestSuiteBuilder$FailedToCreateTests:
Error in testSuiteConstructionFailed:

The class is there. I checked ProGuard, I temporarily deactivated ProGuard. I reduced the test to the absolute minimum:
public class Test_Service2
extends android.test.ServiceTestCase<Service>
{
public Test_Service2 ()
{
super (Service.class);
} // Test_Service2
} // Test_Service2
Has anybody got an idea how this might have come about?
Looking closer I now found the following:

This is part of the original error exception chain but was truncated. The pre-verified exception is not new and yet another pain in Android development.
OK, I found the problem - mostly PEBKAC. So here it is:
I have looked only at the console. But there the error message was truncated. Lesson learned: always check logcat as well.
The real error was the well know pre-verified error which happens when libraries meant for the main application get dragged into test application. Lesson learned: always make sure that libraries are not dragged into the instrumentation test
If you use Maven — like I do — then you can read the details up here Automate Android Test Project, which — for added embarrassment — I wrote myself two weeks ago.
The test is correct and should work.
Be sure that Service and Service.class refer to com.XXX.ws.Service and not android.app.Service.
