想法：实现与腾讯游戏大厅融合自身开发游戏的方式，安装了游戏大厅后对于腾讯自主研发的游戏比如：斗地主，用户无需安装就可以直接使用。
设计思路：把子apk放到assets目录中，在主程序中将此apk拷贝到SD卡中，用动态加载方式去调用。
实现：
public void loadAPK(Bundle paramBundle, String dexpath, String dexoutputpath) {
ClassLoader localClassLoader = ClassLoader.getSystemClassLoader();
DexClassLoader localDexClassLoader = new DexClassLoader(dexpath,
dexoutputpath, null, localClassLoader);
try {
PackageInfo plocalObject = getPackageManager()
.getPackageArchiveInfo(dexpath, 1);
if ((plocalObject.activities != null)
&& (plocalObject.activities.length > 0)) {
String activityname = plocalObject.activities[0].name;
Log.d(TAG, "activityname = " + activityname);
Class localClass = localDexClassLoader.loadClass(activityname);
Constructor localConstructor = localClass
.getConstructor(new Class[] {});
Object instance = localConstructor.newInstance(new Object[] {});
Log.d(TAG, "instance = " + instance);
Method localMethodSetActivity = localClass.getDeclaredMethod(
"setActivity", new Class[] { Activity.class });
localMethodSetActivity.setAccessible(true);
localMethodSetActivity.invoke(instance, new Object[] { this });
Method methodonCreate = localClass.getDeclaredMethod(
"onCreate", new Class[] { Bundle.class });
// Method methodonCreate = localClass.getDeclaredMethod("init", new Class[]{String.class});
methodonCreate.setAccessible(true);
methodonCreate.invoke(instance, paramBundle);
}
return;
} catch (Exception ex) {
ex.printStackTrace();
}
}
采用以上方法在外置SD卡（/mnt/sdcard/）上可以启动子apk，但在内置SD卡（/storage/sdcard0）中无法启动，错误信息如下：
java.lang.IllegalArgumentException: Optimized data directory /storage/sdcard0 is not owned by the current user. Shared storage cannot protect your application from code injection attacks.
大家是否有遇到过类似的问题，还请大家不吝赐教，谢谢。
