Tinker是微信官方的Android热补丁解决方案，它支持动态下发代码、So库以及资源，让应用能够在不需要重新安装的情况下实现更新。当然，你也可以使用Tinker来更新你的插件。
1.拷贝build.gradle文件从https://github.com/Tencent/tinker/tree/master/tinker-sample-android

def javaVersion = JavaVersion.VERSION_1_7
2.拷贝官方的代码
a.png
需要注意的是必须使用SampleApplicationLike作为自己的Application,并且在注解上面替换成自己的包名
@DefaultLifeCycle(application = "{自己的包名}.SampleApplication",
flags = ShareConstants.TINKER_ENABLE_ALL,
loadVerifyFlag = false)
3.在AndroidManifest文件中修改
android:name=".app.SampleApplication"
添加service:
4.打开studio右侧的Gradle里,双击assemableDebug
a.png
这时在build/bakApk下生成了二个文件
b.png
用它们的文件名替换App里面gradle下的文件名
b.png
5.修改MainActivity代码
我的电脑adb指令不太好使不知道什么原因,用小米6usb连接不可以直接连接电脑传数据,要打开开发者选项进行设置如下:
Screenshot_2018-08-25-18-41-07-574_com.android.se.png
这样就能看到下面二个文件夹
Z@U}2J@I`C3P73S_3}}ZNJ6.png
我们把刚刚生成的apk文件拷贝到手机里的Pictures文件夹里,同时修改MainActivity关于生成路径的代码:
TinkerInstaller.onReceiveUpgradePatch(getApplicationContext(),
Environment.getExternalStorageDirectory().getAbsolutePath() + "/Pictures/patch_signed_7zip.apk");
6.运行拷贝到手机的apk效果如下:
Screenshot_2018-08-25-18-50-35-465_com.chinamall2.png
这时我们修改代码,在布局里面加了一行修复成功,然后双击TinkerPathchDebug
16$HW0C21}5%_4R3FE`3FD1.png
在build/outputs/apk/tinkerPatch下面看到patch_signed_7zip.apk的文件拷贝到我们手机的内存卡里的Pictures里
a.png
MainActivity代码:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void patch(View view){
TinkerInstaller.onReceiveUpgradePatch(getApplicationContext(), Environment.getExternalStorageDirectory().getAbsolutePath() + "/Pictures/patch_signed_7zip.apk");
}
public void kill(View view){
ShareTinkerInternals.killAllOtherProcess(getApplicationContext());
android.os.Process.killProcess(android.os.Process.myPid());
}
}
这时我们点击PATCH按钮并没什么卵用,log信息如下:
DefaultLoadReporter: patch loadReporter onLoadPatchListenerReceiveFail: patch receive fail: /storage/emulated/0/Pictures/patch_signed_7zip.apk, code: -2
原因是文件读写权限没有开
如果时api22以上还要在手机的权限管理里面手动打开文件读写权限
我们再次运行:弹出patch success,please restart process代表修复成功
