这是我见过的最奇怪的错误,在我发现数据库泄露错误之后我通过使用静态实例来解决它,现在我的活动崩溃但不是每次只有当我多次使用它并使用其他活动时回到它会崩溃与

使用此静态实例时我的活动代码是
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);
}
我已经搜索了很多没有运气的解决方案,所以请任何帮助都是宝贵的
