java - 无法找到签名中引用的类(Landroid/sec/multiwindow/MultiWindow；)

Question

这是我见过的最奇怪的错误，在我遇到数据库泄漏错误后，我通过使用静态实例解决了它，现在我的 Activity 崩溃了，但不是每次都崩溃，只有当我多次使用它并使用另一个 Activity 时回到它，它会崩溃并显示下面的 logcat

使用此静态实例时我的 Activity 的代码是这样的

protected void onStart() {
        super.onStart();

        try {
            if (DBconnection.getInstance(getApplicationContext()).hasData("Standing")) {
                try {

                    StandingDataList = DBconnection.getInstance(getApplicationContext()).GetAllStanding();
                    Standing_adapter = new ExpandableAdapter(getApplicationContext(), StandingDataList);
                    Standing_ListView.setAdapter(Standing_adapter);
                    Standing_adapter.notifyDataSetChanged();
                } catch (Exception e) {
                    e.getMessage();
                }

这是我的数据库助手类

public class DBconnection extends SQLiteOpenHelper {
    public static final String DBName="my.db";
    public static final int Version=1;
    private static DBconnection mInstance = null;



    public static DBconnection getInstance(Context ctx) {
        if (mInstance == null) {
            mInstance = new DBconnection(ctx.getApplicationContext());
        }
        return mInstance;
    }
    private DBconnection(Context context) {
        super(context, DBName, null, Version);

    }

我已经寻找了很多解决方案但没有运气，所以请任何帮助将是宝贵的

SEC 是三星电子公司。这看起来像是他们的内置时钟应用程序的问题，而不是您的问题。
