[Sudheer NL]

Hi,

I am trying to run a simple project to launch facebook native app on emulator with Android 4.3 on Windows 7, I am blocked with the same error as mentioned in below link, tried suggested solutions but it didn't work. Has anyone faced similar issue?

I have followed all the steps as mentioned in below link to setup the project (re-sign the apk with debug key, etc,..) https://code.google.com/p/robotium/wiki/RobotiumForAPKFiles

logcat error:

12-02 00:55:16.040: E/AndroidRuntime(1037): Caused by: java.lang.ClassNotFoundException: Didn't find class "com.facebook.katana.LoginActivity" on path: DexPathList[[zip file "/system/framework/android.test.runner.jar", zip file "/data/app/com.example.webview.test-2.apk", zip file "/data/app/com.example.webview-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.example.webview.test-2, /data/app-lib/com.example.webview-1, /system/lib]]

code:

package com.facebook.test;

import android.test.ActivityInstrumentationTestCase2;

import com.jayway.android.robotium.solo.Solo;

public class FacebookNativeAppLoginTest extends

ActivityInstrumentationTestCase2 {

private static final String LAUNCHER_ACTIVITY_FULL_CLASSNAME = "com.facebook.katana.LoginActivity";

private static final String TARGET_PACKAGE_ID ="com.facebook.katana";

private static Class launcherActivityClass;

static {

try {

launcherActivityClass = Class

.forName(LAUNCHER_ACTIVITY_FULL_CLASSNAME);

} catch (ClassNotFoundException e) {

throw new RuntimeException(e);

}

}

@SuppressWarnings({ "unchecked", "deprecation" })

public FacebookNativeAppLoginTest() throws ClassNotFoundException {

super(launcherActivityClass);

}

private Solo solo;

@Override

protected void setUp() throws Exception {

// setUp() is run before a test case is started.

// This is where the solo object is created.

solo = new Solo(getInstrumentation(), getActivity());

}

@Override

public void tearDown() throws Exception {

// tearDown() is run after a test case has finished.

// finishOpenedActivities() will finish all the activities that have

// been opened during the test execution.

solo.finishOpenedActivities();

}

/**

* A test that searches for Robotium and asserts that Robotium is found.

*/

public void testNativeLoginFacebook() {

solo.sleep(3000);

solo.clearEditText(0);

solo.enterText(0, "login_signup");

// solo.enterText("login_username", "login_signup");

}

}

Android manifest file:

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.facebook.test"

    android:versionCode="1"

    <instrumentation

    <application

        android:label="@string/app_name" >

        <uses-library android:name="android.test.runner" />

    </application>

</manifest>

Thanks,

The issue was due to the corrupted Facebook APK file, when I tried with the new apk file, issue is resolved.
