Android - 应用程序在Pre-Lollipop设备上崩溃

Question

My app is running well on Lollipop devices but it keep crashing on prior to version Lollipop. I have simply implemented a banner add in my application with the following code through google documention

    // Request for Ads
           AdRequest adRequest = new AdRequest.Builder()

                  // Add a test device to show Test Ads
                 .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                 .build();

         // Load ads into Banner Ads
         mAdView.loadAd(adRequest);

using

    compileSdkVersion 23
    buildToolsVersion "23.0.1"

manifest

  <meta-data
             android:name="com.google.android.gms.version"
             android:value="@integer/google_play_services_version" />

         <activity
             android:name="com.google.android.gms.ads.AdActivity"
          android:configChanges="keyboard|keyboardHidden
   |orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />

Error

Please help me out to get out from this problem.

Answer 1

After expanding more than a hour on problem, I found that I have to do some modification in MyApplication Class like this:

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        // register with Active Android
        ActiveAndroid.initialize(this);
    }

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }
}

I have overriden the attachbaseContext method and all works fine now.

Answer 2

+) Building Apps with Over 65K Method will cause this Error.

+) When your application and the libraries it references reach a certain size ( DEX file of your application can have total number of methods upto 65,536 including Android framework methods, library methods, and methods in your own code), you encounter build errors that indicate your app has reached a limit of the Android app build architecture.

+) To resolve it, include Multidex Configuration in your build.gradle like the highlighted one in picture, along with this override the attachBaseContext(Context base) method in your Application class with the below content.

public class YourParentApplication extends Application {

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
 }
}

Add this in you Androidmanifest.xml:

<application
    android:name=".YourParentApplication"
    android:allowBackup="true"
    android:icon="@drawable/radiius_logo"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:theme="@style/MyMaterialTheme">

Answer 3

You should lower the API in your AndroidManifest.xml Lollipop is API 21.

Check this out: API Levels Example:

   defaultConfig {
        applicationId "com.package.name"
        minSdkVersion 11
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }

Answer 4

reduce your minSdkversion to that version you want to give support

in gradle file of your project

As below

minSdkVersion 10
