即使所有的努力都付诸东流那又怎样
或许你遇到过这样的情况——新版本的app刚提交应用市场没多久，突然发现有一个很严重的bug。这时候该怎么办呐，传统的方式就是修复bug重新提交应用市场，且不说审核需要时间，对用户也是极大的伤害。热修复恰好能解决这样的问题，其实大厂已经开源了很多热修复框架。bugly推出热修复框架已经有一段时间了，腾讯出品，必属于精品，不用担心会出大的问题。下面我来讲一下集成的过程。
https://bugly.qq.com/docs/user-guide/instruction-manual-android-hotfix/?v=20161206145314 这个是官方的文档，不过你若是按照官方文档一步步做下去，不会发现根本不行。
-1- 工程根目录下“build.gradle”文件中添加
<pre>
// tinker gradle插件
classpath ('com.tencent.tinker:tinker-patch-gradle-plugin:1.7.5')
// tinkersupport插件
classpath "com.tencent.bugly:tinker-support:latest.release"
task wrapper(type: Wrapper){
gradleVersion = "2.14.1"
}
</pre>
-2-自定义ApplicationLike,把之前Application中的初始化方法全部都搬到这个类中，Appid替换成bugly上自己项目的Appid
<pre>
public class SampleApplicationLike extends DefaultApplicationLike {
public static final String TAG = "Tinker.SampleApplicationLike";
public SampleApplicationLike(Application application, int tinkerFlags,
boolean tinkerLoadVerifyFlag, long applicationStartElapsedTime,
long applicationStartMillisTime, Intent tinkerResultIntent, Resources[] resources,
ClassLoader[] classLoader, AssetManager[] assetManager) {
super(application, tinkerFlags, tinkerLoadVerifyFlag, applicationStartElapsedTime,
applicationStartMillisTime, tinkerResultIntent, resources, classLoader,
assetManager);
}
@Override
public void onCreate() {
super.onCreate();
Bugly.init(getApplication(), "Appid", true);
}
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
@Override
public void onBaseContextAttached(Context base) {
super.onBaseContextAttached(base);
MultiDex.install(base);
Beta.installTinker(this);
}
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public void registerActivityLifecycleCallback(Application.ActivityLifecycleCallbacks callbacks) {
getApplication().registerActivityLifecycleCallbacks(callbacks);
}
}
</pre>
-3-自定义Application
<pre>
public class App extends TinkerApplication{
public App() {
super(ShareConstants.TINKER_ENABLE_ALL, "SampleApplicationLike带包名地址",
"com.tencent.tinker.loader.TinkerLoader", false);
}
}
</pre>
-4-AndroidManifest.xml配置
-
1. 权限配置
<pre>
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_LOGS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
</pre> -
2.配置FileProvider（Android N之后配置,若是N之前这步不用配置也可以
<pre>
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.tencent.bugly.hotfix.fileProvider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
</pre>
provider_paths文件内容如下
<pre>
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="beta_external_path" path="Download/"/>
<external-path name="beta_external_files_path" path="Android/data/"/>
</paths>
</pre>
-5-在到app目录下新建
keep_in_main_dex.txt对应的内容如下:
<pre>
you can copy the tinker keep rule at
build/intermediates/tinker_intermediates/tinker_multidexkeep.pro
-keep class com.tencent.tinker.loader.** {
*;
}
-keep class com.tencent.bugly.hotfix.SampleApplication {
*;
}
-keep public class * implements com.tencent.tinker.loader.app.ApplicationLifeCycle {
*;
}
-keep public class * extends com.tencent.tinker.loader.TinkerLoader {
*;
}
-keep public class * extends com.tencent.tinker.loader.app.TinkerApplication {
*;
}
here, it is your own keep rules.
you must be careful that the class name you write won't be proguard
but the tinker class above is OK, we have already keep for you!
</pre>
-6-app目录下的build.gradle文件配置

特别注意下面的三块地方:
release.keystore和debug.keystore换成你自己签名，当然对应的storePassword，keyAlias和keyPassword也要做对应的修改
这两块在热更新时要用app-release-1209-11-41.apk对应是要修复的apk，
修复版和线上版本tinkerId要一致。
-7-最后别忘了加上混淆
<pre>
第三方的bugly
-dontwarn com.tencent.bugly.**
-keep public class com.tencent.bugly.*{;}
</pre>
-8-接下来就可以生成测试包了，你可以造一个bug来测试，然后运行生成测试包，不过这里的运行跟以往不同，按下面点击右侧的Gradle，若出现Nothing to show，那就点一下我红圈标注的部分
然后运行assembleRelease生成测试包
测试包在下图所示的位置
然后把测试包上传，可以上传到测试分发，然后将app下载下来，看看是否存在你故意设置的bug，如果本身就没bug就搞笑了。
-9-然后生成修复包
将你故意设置的bug修复，注意我上面说的地方，修改ext下oldApp的路径。然后运行tinkerPatchRelease生成修复包。
修复包生成的位置在patch目录下
然后将发布新补丁，补丁可能需要1到2分钟生效。重新运行你之前下载的app，注意这里需要2次启动才能生效。看看之前的bug是否已在不知不觉中修复。
