1. Turn off grammar checking

When Android applications are packaged, there will be a series of syntax checks, such as the placement of a layout file, which is cumbersome;

In build. Gradle under the module, configure as follows: check the syntax and ignore some minor syntax errors;

android {
    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
}

2. Log processing

According to the compilation type buildconfig.debug in the current compilation configuration, select whether to print the log;

public final class BuildConfig {
  public static final boolean DEBUG = Boolean.parseBoolean("true");
  public static final String APPLICATION_ID = "cn.zkhw.midi";
  public static final String BUILD_TYPE = "debug";
  public static final int VERSION_CODE = 1;
  public static final String VERSION_NAME = "0.1";
}

If the current version is release, the value of buildconfig.debug is false;

Example of development log tool class log:

public class L {

    public static void i(String TAG, String msg) {
        if (BuildConfig.DEBUG)
            Log.i(TAG, msg);
    }
}

3. Release compiler optimization configuration

In general, the release release version needs the following configuration;

android {
    buildTypes {
        debug {
        }

        release {
            zipAlignEnabled true     
            shrinkResources true    
            minifyEnabled true      
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
