title: Instrumentation run failed due to 'Process crashed.'
body: <p>I wanted to run the following test:</p>
  
  <pre><code>package com.xxx.yyy;
  
  import android.content.Context;
  import androidx.test.InstrumentationRegistry;
  import androidx.test.runner.AndroidJUnit4;
  
  import org.junit.Test;
  import org.junit.runner.RunWith;
  
  import static org.junit.Assert.*;
  
  /**
   * Instrumented test, which will execute on an Android device.
   *
   * @see &lt;a href="http://d.android.com/tools/testing"&gt;Testing documentation&lt;/a&gt;
   */
  @RunWith(AndroidJUnit4.class)
  public class ExampleInstrumentedTest {
      @Test
      public void useAppContext() {
          // Context of the app under test.
          Context appContext = InstrumentationRegistry.getTargetContext();
  
          assertEquals("com.xxx.yyy", appContext.getPackageName());
      }
  }
  </code></pre>
  
  <p>But I get the error in the console:</p>
  
  <pre><code>$ adb shell am instrument -w -r   -e debug false -e class 'com.xxx.yyy.ExampleInstrumentedTest' com.xxx.yyy.test/android.support.test.runner.AndroidJUnitRunner
  Client not ready yet..
  Started running tests
  Test running failed: Instrumentation run failed due to 'Process crashed.'
  Empty test suite.
