Going through the classes AnnotationNode and AnnotationVisitor I noticed that there is a api argument passed to the super(api) of AnnotationVisitor which was supposed to be one of Opcodes#ASM4 or Opcodes#ASM5 or Opcodes#ASM6 or Opcodes#ASM7 but the constructor was only accepting the first two.
I noticed that there are two dependencies of org.ow2.asm:asm with two different versions org.ow2.asm:asm:7.0 and org.ow2.asm:asm:5.0.4 which was the source of problem.
To resolve the issue you must force the Gradle to import only the 7.0 version like this:
android {
allprojects {
configurations {
all {
resolutionStrategy {
force "org.ow2.asm:asm:7.0"
}
}
}
}
}

Robolectric test fails when ProgressBar is added (sdk 26)

I'm facing issue with running robolectric test cases with sdk 26. Test are running fine, but when I add a ProgressBar to the respective layout, all test cases for that fragment (which contains the progress bar layout) starts to fail.
Also if I change that sdk to 25 using #Config, test is passing even with ProgressBar in the layout.
Robolectric version used:
testCompile 'org.robolectric:robolectric:3.4.2'
testCompile 'org.robolectric:shadows-multidex:3.3.2'
testCompile 'org.robolectric:shadows-support-v4:3.3.2'
Android Support libraries : 26
Please find below the log for the failure issue:

Clicking a recycler view list item (with Espresso UI automation test) on a medium size phone works fine

edit
Now I see some crucial bit of info from stack-trace, but still does not resolve why this error occurs on tablet only
caused by: java.lang.IllegalStateException: No view holder at position: 1

Call check before perform action.
onView(withId(R.id.rv_recycler_view)).check(ViewAssertions.matches(isDisplayed()));
onView(withId(R.id.rv_recycler_view))
.perform(actionOnItemAtPosition(i, click()));

java.lang.NoClassDefFoundError: org/apache/oltu/oauth2/client/request/OAuthClientRequest$TokenRequestBuilder

Below mentioned error occurred while running Junit .
Architecture of app in same as
https://github.com/ribot/android-boilerplate
I have used swagger-codegen to generate my client code for retrofit
Test Case
#RunWith(MockitoJUnitRunner.class)
public class LoginPresenterTest {
#Mock
LoginView loginView;
#Mock
DataClient dataClient;
private LoginPresenter loginPresenter;
#Before
public void setUp() {
loginPresenter = new LoginPresenter();
loginPresenter.attachView(loginView);
}
#Test
public void onLoginSuccess() {
loginPresenter.doLogin("abc", "abc");
}
}
Can some one help me to find out the cause .

Your client side misses "Apache Oltu OAuth 2.0 Client" dependency and thus the error:
java.lang.NoClassDefFoundError:
org/apache/oltu/oauth2/client/request/OAuthClientRequest$TokenRequestBuilder
For Gradle Build use:
compile 'org.apache.oltu.oauth2:org.apache.oltu.oauth2.client:1.0.1'
For Maven use:
<dependency>
<groupId>org.apache.oltu.oauth2</groupId>
<artifactId>org.apache.oltu.oauth2.client</artifactId>
<version>1.0.1</version>
</dependency>

Cannot instantiate OrmLite helper in a unit test class in Android Studio

This is my code:
#RunWith(MockitoJUnitRunner.class)
public class OrmLiteTest {
OrmLiteDatabaseHelper databaseHelper;
#Mock
Context mMockContext;
#Before
public void setup() {
mMockContext = Mockito.mock(Context.class);
databaseHelper = OpenHelperManager.getHelper(mMockContext,
OrmLiteDatabaseHelper.class);
}
I get the following exception when I run the test:
java.lang.IllegalStateException: Could not construct instance of helper class class com.example.myapp.application.OrmLiteDatabaseHelper

You are trying to invoke a method (or similar) on an object which is null in the OrmLiteSqliteOpenHelper.java, line 310
As you didn't share that code, that's all we can say...
Caused by: java.lang.NullPointerException
at com.j256.ormlite.android.apptools.OrmLiteSqliteOpenHelper.openFileId(OrmLiteSqliteOpenHelper.java:310)
Oh, and the line...
mMockContext = Mockito.mock(Context.class);
...should be removed, since the #RunWith(MockitoJUnitRunner.class) will already inject a mock there, no need to create one manually.
