Android Studio通過配置build.gradle參數(shù)設(shè)置全局的Log開關(guān)

在app中的build.gradle中，在編譯后會生成一個BuildConfig的類,這個類包含了一些當(dāng)前編譯類型的基本參數(shù)。如：

public final class BuildConfig {
  public static final boolean DEBUG = Boolean.parseBoolean("true");
  public static final String APPLICATION_ID = "com.ateqi.xhttp";
  public static final String BUILD_TYPE = "debug";
  public static final int VERSION_CODE = 1;
  public static final String VERSION_NAME = "1.0";
}

BuildConfig中的DEBUG參數(shù)其實是通過isDebuggable參數(shù)來控制的

一般debug類型apk是默認(rèn)BuildConfig.DEBUG為true，release類型BuildConfig.DEBUG為false。

buildTypes {
    release {
        ...
        isDebuggable = false    //默認(rèn)false，可不寫
    }
    debug {
        ...
        isDebuggable = true    //默認(rèn)true，可不寫
    }
}

當(dāng)然我們還可以在build.gradle中自定義一個變量控制，如：

defaultConfig {
    ...
    buildConfigField("boolean", "IS_SHOW_LOG", "false")//TODO Log日志開關(guān)
}

會在BuildConfig這個類中生成一個變量，變量名為IS_SHOW_LOG，值為false

public final class BuildConfig {
  public static final boolean DEBUG = Boolean.parseBoolean("true");
  public static final String APPLICATION_ID = "com.ateqi.xhttp";
  public static final String BUILD_TYPE = "debug";
  public static final int VERSION_CODE = 1;
  public static final String VERSION_NAME = "1.0";
  // Field from default config.
  public static final boolean IS_SHOW_LOG = false;
}

gradle8.x默認(rèn)禁用了生成BuildConfig

項目中使用productFlavors配置了buildConfigField 提示功能禁用
解決辦法：開啟buildConfig

buildFeatures {
    buildConfig = true
}
