收缩Android使崩溃

我已经升级了Android Studio

因此，升级到最新版本后，我用以下内容更新了我的应用程序：

“shrinkResources true”

，

“minifyEnabled true”

不幸的是，我在一些设备上崩溃了，没有收缩，一切都很完美

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 android.os.AsyncTask$2.call (AsyncTask.java:333)
  at java.util.concurrent.FutureTask.run (FutureTask.java:266)

下面是发生崩溃的名为

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'

解决办法可能是什么？谢谢

在发布模式中添加“可调试的true”
或

将proguard android优化proguard更改为“proguard android”
它对我有用
你是否为你的应用程序设置了proguard规则。如果没有，这就是你的出发点。检查是否有任何帮助
