Question

由于未知原因，Android Studio项目中的Java文件从另一个项目的另一个包中有一个BuildConfig类的子箭头

/**
 * Automatically generated file. DO NOT MODIFY
 */
package alsayed.aly.maintenanceplaner;

public final class BuildConfig {
  public static final boolean DEBUG = Boolean.parseBoolean("true");
  public static final String APPLICATION_ID = "alsayed.aly.maintenanceplaner";
  public static final String BUILD_TYPE = "debug";
  public static final String FLAVOR = "";
  public static final int VERSION_CODE = 1;
  public static final String VERSION_NAME = "1.0";
}

我尝试还原它，但由于现在刚刚创建的文件，它无法正常工作。

在构建时，Gradle会生成BuildConfig类，以便您的应用代码可以检查有关当前构建的信息。

您还可以使用buildConfigField（）方法从Gradle构建配置文件中将自定义字段添加到BuildConfig类中，并在应用程序的运行时代码中访问这些值。同样，您可以使用resValue（）添加应用程序资源值。

 android {
  ...
  buildTypes {
    release {
      // These values are defined only for the release build, which
      // is typically used for full builds and continuous builds.
      buildConfigField("String", "BUILD_TIME", "\"${minutesSinceEpoch}\"")
      resValue("string", "build_time", "${minutesSinceEpoch}")
      ...
    }
    debug {
      // Use static values for incremental builds to ensure that
      // resource files and BuildConfig aren't rebuilt with each run.
      // If they were dynamic, they would prevent certain benefits of
      // Instant Run as well as Gradle UP-TO-DATE checks.
      buildConfigField("String", "BUILD_TIME", "\"0\"")
      resValue("string", "build_time", "0")
    }
  }
}

在您的应用代码中，您可以按以下方式访问属性：

Log.i(TAG, BuildConfig.BUILD_TIME);
Log.i(TAG, getString(R.string.build_time));

我无法打开班级，只是找到一个BuildConfig文件
