Shrink Android 使 Crash

Question

我已经升级了 Android Studio。

因此，将其升级到最新版本后，我更新了我的应用程序： "shrinkResources true"，"minifyEnabled true"

不幸的是，我在某些设备上崩溃了，没有缩小一切都可以完美运行。

以下是崩溃日志：

java.lang.RuntimeException: 

  at android.os.AsyncTask$3.done (AsyncTask.java:354)
  at java.util.concurrent.FutureTask.finishCompletion (FutureTask.java:383)

  at java.util.concurrent.FutureTask.run (FutureTask.java:266)

下面是发生崩溃的名为WallpaperPreference 的类。

public class WallpaperPreference {
private Context context;
private SharedPreferences sharedPreferences;

public WallpaperPreference(Context context) {
    this.context = context;

    sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context);
}

public void setLWPDay(int value) {
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putInt(Base.LWP_JSON_DAY, value);
    editor.apply();
}

public int getLWPDay() {
    return sharedPreferences.getInt(Base.LWP_JSON_DAY, 0);
}

}

我用过：

compileSdkVersion 29
buildToolsVersion '29.0.3'

可能的解决方案是什么？谢谢。

Answer 1

1. 在发布模式下添加“debuggable true”

或

1. 将 proguard-android-optimize proguard 更改为“proguard-android”

它对我有用
