Android uses Gradle for multi-channel Packaging

Android uses Gradle for multi-channel Packaging

Android development is complete. For an open application, we need to publish it to different application markets. At the same time, we also need to count the downloads of users in different markets. (Obtain different values of apk in different markets after starting the application to differentiate them)

Here is a specific example:
1. Add the meta-data tag to the application of AndroidManifest. xml.

2. Modify the build. gradle file and add it to android {}.

Android {// package channel List productFlavors {wandoujia {channels = [APP_CHANNEL_VALUE: "pods"]} cn360 {channels = [APP_CHANNEL_VALUE: "360"]} baidu {channels = [APP_CHANNEL_VALUE: "Baidu"]} tencent {manifestPlaceholders = [APP_CHANNEL_VALUE: ""]} sougou {manifestPlaceholders = [APP_CHANNEL_VALUE: "sogou market"]}

Or use the following method to directly use the name of flavor as $ {APP_CHANNEL_VALUE}

Android {// package channel List productFlavors {wandoujia {} cn360 {} baidu {} tencent {} sougou {} // batch processing, directly use the name of flavor as the value of APP_CHANNEL_VALUE productFlavors. all {flavor-> flavor. manifestPlaceholders = [APP_CHANNEL_VALUE: name]}

This completes. Execute gradle assumerelease to have a cup of tea and wait.
After that, you can view the channel packages in build/outputs/apk.

Available commands for assemble include:

Gradle assembleDebug // All Debug Versions gradle javaserelease // All Release versions gradle assembleBaidu // The Debug and Release versions of the specified channel gradle assembleBaiduDebug // The Debug version of the specified channel gradle Release // The specified channel the Release version of gradle build // Debug and Release versions of all channels

Add my MainActivity and build. gradle.

Package com. example. myandroid; import android. app. activity; import android. content. pm. applicationInfo; import android. content. pm. packageManager; import android. content. pm. packageManager. nameNotFoundException; import android. OS. bundle; import android. widget. toast;/*** application portal ** @ author SHANHY ([email protected]) * @ date December 30, 2015 */public class MainActivity extends Activity {@ Override protected void onC Reate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. activity_main); String channel = getAppMetaData ("APP_CHANNEL"); if (channel! = Null) Toast. makeText (this, channel, Toast. LENGTH_SHORT ). show ();}/*** get metaData under the Application ** @ param name * @ return * @ author SHANHY * @ date January 1, December 30, 2015 */public String getAppMetaData (String meta_name) {try {ApplicationInfo appInfo = this. getPackageManager (). getApplicationInfo (getPackageName (), PackageManager. GET_META_DATA); return appInfo. metaData. getString (meta_name);} catch (NameNotFoundException e) {e. printStackTrace ();} return null ;}}

Complete build. gradle script
