FATAL EXCEPTION : unable to instantiate activity componentInfo in android studio

I have tried every answer for this on Google, but none worked for me.
I have just created an app I Android studio and add .jar file and simply running it.
But the app crashes leaving with below error message.

Check in your manifest file if you have declared the class as an activity.
If missing, do it.
Clean and REBUILD the code.
Hope this helps.

app crash when first run on Android 4.4

I am using Android studio to build my app
I have 2 emulators the first uses Android 6.0 and the second uses Android 4.4
My app runs perfectly on the Android 6.0 but when I try it on 4.4 it crashes immediately.
I tried debugging the app by putting break point on the first like but it does not reach the first line. it crashes stright away.
The error message I got is not that clear, I dont know what the problem is and how to fix it.

Try to use this
STEP 1:
Go to your dependency and add this line
compile 'com.android.support:multidex:1.0.1'
and in the defaultConfig Section add this
defaultConfig {
minSdkVersion xx
targetSdkVersion xx
versionCode x
multiDexEnabled true
}
Then
Create a class called e.g MyApp.java
public class MyApp extends Application{
#Override
public void onCreate() {
super.onCreate();
}
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
STEP :2
Go to your manifest and do the following in the Application Tag
<application
android:name="MyApp"
.
.
.
in your gradle, set
multiDexEnabled true
and in Application class:
Extend Application class with MultiDexApplication
#Override
protected void attachBaseContext(Context base) {
MultiDex.install(this);
super.attachBaseContext(base);
}
because MultiDexApplication has not been extended so that it can't include gms and any other dex classes so it's giving error at starting of gms String.
You can refer here for more information on how to use multidex :

Application terminated.
I added Ion through the app's build.gradle as it is stated on the github, compile 'com.koushikdutta.ion:ion:2.+'.
As stated earlier, on higher Android versions it works fine.
It also works fine on a completely clean project with just adding Ion
I now fixed it myself.
I created a new project with the same package name and copied the app folder completely to the new project, it works fine there. Weird!

app is died, Occur ClassNotFoundException on android

when I run my app, app died and occur classNotFoundException.
perhaps, gradle problem ?
compileSdkVersion =22
buildToolsVersion =21.1.2
minSdkVersion =19
targetSdkVersion =22
I think code problem.
settings, or gradle problem.
please advice for me.

So, thoughts?
I was also trying to implement it and got the same error .After lot of effort I was able to run it but received the similar error as you have received .
I resolved the issue by
1:Close and start your eclipse .
2: copying the v4 jar of main project in all the library projects and deleting the existing ones .
The error comes due to mismatch of supportv4jar. Make all the supportv4jar of same version
3:after that Delete the gen and bin folder and clean the project and run .
