動(dòng)態(tài)加載需要反射的知識(shí)
一、加載未安裝apk 1、 首先得有宿主APK (ta)
下面是按鈕觸發(fā) 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, "吃飯吧！！！"); //調(diào)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,復(fù)制到SD卡根目錄就可以了 跑步
/** * 被調(diào)起的未安裝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; }}：參考 http://www.cnblogs.com/over140/archive/2012/03/29/2423116.html
3、加載插件Activity并實(shí)現(xiàn)應(yīng)用內(nèi)跳轉(zhuǎn) http://blog.csdn.net/singwhatiwanna/article/details/22597587 的代碼整理 https://github.com/BlogForMe/DynamicLoadMe dynamicloadclient和dynamicloadhost部分
二、動(dòng)態(tài)加載dex文件
:問題 在Ubuntu git clone(https://github.com/BlogForMe/dynamic-load-apk) 這個(gè)項(xiàng)目，然后open之后，報(bào)出這樣一個(gè)錯(cuò)誤 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)
我的解決方案： 到home 目錄下 ctrl + H,然后出現(xiàn).gradle隱藏文件，刪除 ，然后讓studio重新編譯。 配置好后要是還跑不了，把Intant Run關(guān)了
