Question

尝试在具有多个活动的应用程序中使用CacheWord来处理我的数据库加密密码我随机得到活动泄漏ServiceConnection的错误...最初绑定在此处。

我认为这个问题是由于在调用onDestroy（）时没有彻底断开服务的连接。但我不知道该怎么做。

我的MainActivity的结构：

package de.my.app;

import info.guardianproject.cacheword.CacheWordActivityHandler;
import info.guardianproject.cacheword.CacheWordHandler;
import info.guardianproject.cacheword.ICacheWordSubscriber;

public class Home extends Activity implements ICacheWordSubscriber {

private static final String TAG = Home.class.getSimpleName();
private Menu mainMenu;

// removed more definitions

private CacheWordActivityHandler mCacheWord;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    SQLiteDatabase.loadLibs(this);
    mCacheWord = new CacheWordActivityHandler(this, this); 

}

@Override
protected void onPause() {
    super.onPause();
    mCacheWord.onPause();

    Log.d(TAG,"onPause()");
}

@Override
protected void onResume() { 
    super.onStart(); 
    mCacheWord.onResume();

    Log.d(TAG,"onResume()");
}

private void closeDatabase()
    {
        Log.d(TAG,"closeDatabase()");

        if (dbHandler != null) {
            dbHandler.close();
            dbHandler = null;
        }
    }

void showLockScreen() {

    Log.d(TAG,"showLockScreen()");

    Intent intent = new Intent(this, LockScreenActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    intent.putExtra("originalIntent", getIntent());
    startActivity(intent);
    finish();
}

void lock() {

    Log.d(TAG,"lock()");

    closeDatabase();
    System.gc();
    showLockScreen();
}

private void unlockDatabase()
{

    Log.d(TAG,"unlockDatabase()");

    dbHandler = new TBOpenHandler(mCacheWord, this);

    try
    {

        dbHandler.open();

    } catch (Exception e)
    {
        e.printStackTrace();
        Toast.makeText(this, getString(R.string.err_pass), Toast.LENGTH_LONG).show();
    }
}

@Override
public void onCacheWordUninitialized() {
    Log.d(TAG, "onCacheWordUninitialized()");
    showLockScreen();
}

@Override
public void onCacheWordLocked() {
    Log.d(TAG, "onCacheWordLocked()");
    lock();
}

@Override
public void onCacheWordOpened() {
    Log.d(TAG, "onCacheWordOpened()");
    unlockDatabase();

    if (dbHandler.isOpen()) { 
        inhalt();
    }
}

private void inhalt() {

    // removed the content

}

}

还有错误消息：

有没有办法解决这个问题？

Answer 1

答案有点迟，但你永远不知道。

我遇到了同样的问题，因为我在AndroidManifest中没有提供正确的服务。

我的意思是，我有服务，但是，当我做了名称包的重构时，eclipse改变了服务的包。

所以请看看AndroidManifest，并确保你有这样的方式：

<service
     android:name="info.guardianproject.cacheword.CacheWordService"
     android:enabled="true"
     android:exported="false" />

使用CacheWord的活动泄露了ServiceConnection
