Android Studio multi-channel packaging, Debug formal package, Build.gradle parsing

1, explain the Build.gradle file. 1.1 Root directory Android

1.1.1
Defaultconfig is the root directory of Android, you can configure the package name and other information, if the Androidmainfest.xml is also configured, to Defaultconfig prevail.
1.1.2
Signingconfigs is the root directory of Android and can be configured with signatures such as:

When debugging, if you want to use a formal signature package can be configured in the BuildType.

buildtypes {    Debug {        signingconfig signingconfigs.release    }    release {        false         proguardfiles getdefaultproguardfile (' proguard-android.txt'proguard-rules.pro '     }}

1.1.3
Multi-channel packaging, modifying the Meta-data value of Androidmainfest.
The Androidmainfest configuration is as follows:

${value} is dynamically configured.

Android : Name= ". MyApplication ">    <meta-data        android: Name= "Channelvalue"  android: value= "${value}" ></meta-data>         

The Build.gradle is configured as follows

productflavors {    Huawei {                manifestplaceholders        =[  Value"Huawei"]    }    Xiaomi                 {         manifestplaceholders =[Value"Xiaomi"}    }

Gets the value of Androidmainnifest value in the code

//Get meta fieldsPublic StaticStringgetmetastring(Context con,String name) {ApplicationInfo AI =null;Try{ai = Con.getpackagemanager (). Getapplicationinfo (Con.getpackagename (), Packagemanager.Get_meta_data);        }Catch(Packagemanager.namenotfoundexception e) {E.printstacktrace ();        } Bundle bundle = AI.MetaData;returnBundle.getstring (name);}

Direct use when packaging

Finally paste the Build.gradle file.
