Error=Unable to find instrumentation info for: ComponentInfo{ } –

Development issue/problem:

I’m trying to get the espresso tests, but I keep getting this error message:

INSTRUMENTATION_STATUS : Error = No information about the device can be found: ComponentInfo{com.mikeestrada.test/android.test.InstrumentationTestRunner}

It worked once, but I can’t seem to recover the reports properly. They were left empty, without checking anything.
I’ve tried many orders, including

adb shell am tool -w -r com.mikeestrada.test/android.test.instrumentationTestRunner


adb shell am tool -w -r com.mikeestrada.test/ TestRunner

Here are my code snippets:

com.mikeestrada.test.package ;

import android.test.ActivityInstrumentationTestCase2;
import android.test.ActivityUnitTestCase;
import android.test.AndroidTestCase;
import android.test.suitebuilder.annotation.LargeTest;
import android.view.view. Look, um..;

import apps.common.testresults.ui.espresso assertion.ViewAssertions;

import junit.framework.Assert ;
import org.hamcrest.Matcher ;

The TestStartScreen public class extends the ActivityInstrumentationTestCase2 {

public TestStartup() {

@LargeTestpublic void testHelloWorld(final Matcher viewMatcher) {// Find/ Find Button/Interaction button1 = onView(ViewMatchers.withId(; // Find ButtonViewInteraction helloWorldText = Espresso.onView(ViewMatchers.withText(Hello world !)); // Find Text

// action
//button1.perform(; // button
helloWorldText.perform(ViewActions.typeText(Bye World!));

// Check
helloWorldText.check(ViewAssertions.matches((ViewMatchers.isDisplayed()))); // The hello text is hidden.

//Espresso.onView(withId( World !))));

build {
repositories {
dependencies {
classpath ‘’
application plugin : android

Deposits {

android {
compileSdkVersion 19
buildToolsVersion 19.0.0

defaultConfig {
minSdkVersion 7
targetSdkVersion 19

compileOptions {
compatibility }

sourceSet {
main {
manifest.srcFile AndroidManifest.xml
assets.srcDirs = [‘assets’]
} } }

dependencies {
compile ‘’
instrumentTestCompile files (‘libs/espresso-1.1-bundled.jar’)
android { default
Config {
} Task wrapper
(type: wrapper) {
gradlerVersion = ‘1.9’

If it means anything – the manifest attributes are colored red, as if IntelliJ doesn’t recognize them.

Any help is welcome, thank you!

How can I solve this problem?

Solution 1:

You need to check which device packages are installed on your device:

Party equipment

Check if com.mikeestrada.test is actually listed there.

Solution 2:

If the device package is missing, install it with the following command:

$ gradle :{$project}:installDebugAndroidTest

Sorting tasks with the installDebugAndroidTest localization

Solution 3:

If you look at your build.gradle file, the problem is actually that you do not have the following configuration under defaultConfig :


Espresso needs GoogleInstrumentationTestRunner to run.

Even with the layered build system, you don’t need the AndroidManifest.xml file for the test project because it’s automatically generated.

Solution 4:

Also, it looks like your application is com.mikeestrada.
So, in AndroidManifest, define android:targetPackage as android:targetPackage=com.mikeestrada.

I hope this helps.

Solution no. 5:

The problem is that you don’t have enough room:

Instrumentation and android: title


Instrumentation and android: name

Solution no. 6:

It looks like you need to make sure the application and test applications are installed.

Good luck!
