Question

I\'m trying the Quickstart: Run a Drive App on Android from Google Drive SDK. I have followed the hole process, but when I ran the app in my devices (real ones), it crashes

I had the same issue with the jtwitter.jar library. If you're running Android Studio, you have to do a clean & build (which AS doesn't truly do right now).

Go to your command line, navigate to your project root and execute ./gradlew clean

BEFORE YOU DO THIS

Ensure that your .jar file is added to your /libs folder (if you're using build 17 or later, it has to be libs, and not lib). Right-click and select Add as Library...

Then you're going to have to edit your build.gradle file (located in your /src directory).

It should look something like this:

buildscript {
    repositories {
        maven { url 'http://repo1.maven.org/maven2' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'
    }
}
apply plugin: 'android'

dependencies {
    compile files('libs/android-support-v4.jar')
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 5
        targetSdkVersion 16
    }
}

Change the dependencies block to look like this:

dependencies {
    compile files('libs/android-support-v4.jar')
    compile files('[path/to/.jar]')
}

Then you can build and run your project.
