动态加载需要反射的知识
一、加载未安装apk
1、 首先得有宿主APK (ta)
下面是按钮触发
String fileName = "TestB.apk";
String apkPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + fileName;
public void ClickIn(View v) {
DexClassLoader classLoader = new DexClassLoader(apkPath, getDir("dex",
Context.MODE_PRIVATE).getAbsolutePath(), null, getClassLoader());
try {
Class TestBClass = classLoader.loadClass("com.hyhy.tb.TestBActivity");
Object TestBActivity = TestBClass.newInstance();
Method getEat = TestBClass.getDeclaredMethod("getEat", String.class);
getEat.setAccessible(true);
Object eat = getEat.invoke(TestBActivity, "吃饭吧!!!"); //调用getEat(String arg);
Toast.makeText(this, eat.toString(), Toast.LENGTH_LONG).show();
} catch (Exception e) {
e.printStackTrace();
}
}
2、插件APK(tb)
把tb命名成TestB.apk,复制到SD卡根目录就可以了
跑步
/**
* 被调起的未安装APK
*/
public class TestBActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public String getEat(String arg) {
return arg;
}
}

3、加载插件Activity并实现应用内跳转

的代码整理

dynamicloadclient和dynamicloadhost部分
二、动态加载dex文件
:问题
在ubuntu git clone(https://github.com/BlogForMe/dynamic-load-apk) 这个项目,然后open之后,报出这样一个错误
Error:Failed to open zip file.
Gradle’s dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)
Re-download dependencies and sync project (requires network)
我的解决方案: 到home 目录下 ctrl + H
,然后出现.gradle隐藏文件,删除
,然后让studio重新编译。
配置好后要是还跑不了,把Intant Run关了
