Bugly implements hot update of APP

Bugly implements thermal repair using Wechat Tinker Technology. Tinker is simplified.

Configuration parameters

Adding plug-in dependencies

Add:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        // The tinkersupport plug-in, where latest.release refers to the latest version number, can also specify a specific version number, such as 1.0.3
        classpath "com.tencent.bugly:tinker-support:latest.release"
    }
}

II. Integrated SDK

gradle configuration

Add (example configuration) to the "build.gradle" file of app module:

dependencies {
      compile "com.android.support:multidex:1.0.1" 
      compile 'com.tencent.bugly:crashreport_upgrade:latest.release'
}

Add:

// Dependent plug-in scripts
apply from: 'tinker-support.gradle'

The contents of tinker-support.gradle are as follows (example configuration):

You need to create the tinker-support.gradle file in the same directory

apply plugin: 'com.tencent.bugly.tinker-support'

def bakPath = file("${buildDir}/bakApk/")

def appName = "app-0111-15-18-41"

/**
* For detailed analysis of plug-in parameters, please refer to
*/
tinkerSupport {

    // Open the tinker-support plug-in with the default value true
    enable = true

    // Specify the archive directory, default value of current module subdirectory tinker
    autoBackupApkDir = "${bakPath}"

    // Whether to enable overlay tinkerPatch configuration function, default value false
    // The tinkerPatch configuration does not take effect after opening, that is, there is no need to add tinkerPatch
    overrideTinkerPatchConfiguration = true

    // When compiling patch packs, you must specify the baseline version of the apk, which defaults to null
    // If null, it means that the patch package is not compiled
    // @{link tinkerPatch.oldApk }
    baseApk =  "${bakPath}/${appName}/app-release.apk"

    // applyMapping corresponding to tinker plug-in
    baseApkProguardMapping = "${bakPath}/${appName}/app-release-mapping.txt"

    // ApplyResource Mapping for the tinker plug-in
    baseApkResourceMapping = "${bakPath}/${appName}/app-release-R.txt"

    // Uniquely identifies the current version
    tinkerId = "1.0.1-base"

    // Whether to open the proxy Application or not, there is no need to modify the Application after setting, the default is false.
    enableProxyApplication = false
}

Initialization of SDK

enableProxyApplication = false

Custom Application

public class SampleApplication extends TinkerApplication {
    public SampleApplication() {
        super(ShareConstants.TINKER_ENABLE_ALL, "com.yiba.test.buglypatch.SampleApplicationLike",
                "com.tencent.tinker.loader.TinkerLoader", false);
    }
}

Custom Application Like

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();
        // SDK initialization is implemented here, and appId is replaced by your appId applied for on the Bugly platform.
        Bugly.init(getApplication(), "900029763", true);
    }


    @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
    @Override
    public void onBaseContextAttached(Context base) {
        super.onBaseContextAttached(base);
        // you must install multiDex whatever tinker is installed!
        MultiDex.install(base);

        // Install tinker
        // TinkerManager.installTinker(this); replace with the method provided by Bugly below
        Beta.installTinker(this);
    }

    @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
    public void registerActivityLifecycleCallback(Application.ActivityLifecycleCallbacks callbacks) {
        getApplication().registerActivityLifecycleCallbacks(callbacks);
    }

}

IV. Android Manifest. XML Configuration

Permission configuration

<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"/>

Activity configuration

<activity
    android:name="com.tencent.bugly.beta.ui.BetaActivity"
    android:theme="@android:style/Theme.Translucent" />

Configure FileProvider (after Android N)

see File

V. Confusion Configuration

To avoid confusion with SDK, add the following configuration to the Proguard confusion file:

-dontwarn com.tencent.bugly.**
-keep public class com.tencent.bugly.**{*;}

If you use the support-v4 package, you also need to configure the following confusion rules:

-keep class android.support.**{*;}

6. Compilation Benchmark Package

Benchmark packages are packages that originally run bug s.

Click the Gradle button in the upper right corner of Android Studio to find the assemble Release task of the project, and double-click to execute the assemble Release task.

When the task is completed, the following files are generated in the build directory:

Repair the base code

Prefix code:

public class BugClass {

    public String bug() {
        String str = "This is a bug";
        str = null;
        Log.e("zhang", "BugClass --> bug--> str length :" + str.length());
        return str;
    }
}

Repair the following code:

public class BugClass {

    public String bug() {
        String str = "This is a bug";
//        str = null;
        Log.e("zhang", "BugClass --> bug--> str length :" + str.length());
        return str + "  , fixed!!!";
    }
}

Call code:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btn = (Button) findViewById(R.id.btn);

        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                BugClass bugClass = new BugClass();
                String bug = bugClass.bug();
                Toast.makeText(MainActivity.this, bug, Toast.LENGTH_SHORT).show();
            }
        });
    }
}

8. Generating patch packs

Modifying appName names and file names need to be consistent. At the same time, tinkerid=1.0.1-base of the reference package is changed to tinkerid=1.0.1-patch of the patch package.
