Question

启用严格模式后，当我尝试在运行于Android Jellybean（4.3）的设备上安装应用程序时，我可以看到以下内存泄漏消息，但是如果我安装运行于android 7.1.2（Android N）的应用程序，则会出现此问题不来我需要在Android 4.3（即软糖）上使用我的应用程序

附加日志和示例应用代码： 这只是警告，而不是内存泄漏。日志：

application1

 for (int i =0 ; i<10 ; i++)

            {
                View view = loadExternalView(packageName,className);

            }

    public synchronized Context loadExternalContext(String packageName)
            throws PackageManager.NameNotFoundException, NullPointerException {

        if (!mCachedContexts.containsKey(packageName)) {
             Context context = mContext.createPackageContext(packageName, CONTEXT_INCLUDE_CODE | CONTEXT_IGNORE_SECURITY);   
                    mCachedContexts.put(packageName, context);
        }
        return mCachedContexts.get(packageName);
    }

    public synchronized View loadExternalView(String packageName, String className)
            throws PackageManager.NameNotFoundException, ClassNotFoundException, ClassCastException, IllegalArgumentException, InstantiationException,
            IllegalAccessException, InvocationTargetException, NoSuchMethodException, NullPointerException {
        Context apkContext = loadExternalContext(packageName);
        Class<?> cls = loadExternalClass(packageName, className);
        return (View) cls.getConstructor(Context.class).newInstance(apkContext);
    }

 public Class<?> loadExternalClass(String packageName, String className)
            throws PackageManager.NameNotFoundException, ClassNotFoundException {    

        String key = packageName + "/" + className;   
        if (!mCachedClasses.containsKey(key)) {
            Context apkContext = loadExternalContext(packageName); 
            String apkName = apkContext.getPackageManager().getApplicationInfo(packageName, 0).sourceDir; 
            PathClassLoader pathClassLoader = new PathClassLoader(apkName, apkContext.getClassLoader()); //actual

            try {
                Class<?> clazz = Class.forName(className, true, pathClassLoader);

                mCachedClasses.put(key, clazz);

            } catch (ClassNotFoundException e) {

            }
        }

        return mCachedClasses.get(key);
    }

应用程序2：

public class DummyView_1 extends RelativeLayout {



    public DummyView_1(Context context){
        super(context);
        loadview();
    }

    public DummyView_1(Context context, AttributeSet attrs){
        super(context, attrs);
        loadview();
    }
    public DummyView_1(Context context, AttributeSet attrs, int defStyle){
        super(context, attrs, defStyle);
        loadview();
    }

    public void loadview(){
        LayoutInflater inflater = LayoutInflater.from(this.getContext());
        inflater.inflate(R.layout.activity_dummy_1, this);
    }
}
