Integrate Devtool to Android

Integrate Devtool to Android

Weex devtools is a custom devtools for weex that implements Chrome Debugging Protocol inspired by Stetho, it is designed to help you quickly inspect your app and debug your JS bundle source in a Chrome web page. To make it work, at first you must integrate devtool to your App. This page will help you integrate devtool to your Android App.

Integrate to Android

Installing Dependencies

Weex Devtools depend on weex_inspector. I strongly recommend you use the latest version since both Weex SDK and devtools are developed iteratively and rapidly. See the release version list here. All the release version will publish to the jcenter repo. There are two choices to install it:

  • From Gradle

    dependencies {
    compile 'com.taobao.android:weex_inspector:0.8.0.0'
    }
  • From source code

    you need to copy the dir of inspector to the same dir of your app and add include ":inspector"in your project’s settings.gradle file just like playground have done, then add dependency in your app’s build.gralde.

    dependencies {
    compile project(':inspector')
    }

Version compatibility

Adding Debug mode switch

The key to control the opening and closing of the debug mode can be summarized as three rules:

No.1: Set the switch and Debugger Server addresses via sRemoteDebugMode and sRemoteDebugProxyUrl.

WXEnvironment class has a pair of static variables mark Weex current debug mode:

public static boolean sRemoteDebugMode; // default close
public static String sRemoteDebugProxyUrl; // Debugger Server addresses

You have to set WXEnvironment.sRemoteDebugMode and WXEnvironment.sRemoteDebugProxyUrl at the right time, for example:

private void initDebugEnvironment(boolean enable, String host) {
WXEnvironment.sRemoteDebugMode = enable;
WXEnvironment.sRemoteDebugProxyUrl = "ws://" + host + ":8088/debugProxy/native";
}

No.2: You must call WXSDKEngine.reload() method when sRemoteDebugMode was changed.

You can control a state of debug mode via the WXEnvironment.sRemoteDebugMode, but you need reset Weex runtime if you changed a state of debug mode.

private void launchInspector(boolean remoteDebug) {
if (WXEnvironment.isApkDebugable()) {
try {
if (mWxDebugProxy != null) {
mWxDebugProxy.stop();
}
HackedClass<Object> debugProxyClass = WXHack.into("com.taobao.weex.devtools.debug.DebugServerProxy");
mWxDebugProxy = (IWXDebugProxy) debugProxyClass.constructor(Context.class, WXBridgeManager.class)
.getInstance(WXEnvironment.getApplication(), WXBridgeManager.this);
if (mWxDebugProxy != null) {
mWxDebugProxy.start();
if (remoteDebug) {
mWXBridge = mWxDebugProxy.getWXBridge();
} else {
if (mWXBridge != null && !(mWXBridge instanceof WXBridge)) {
mWXBridge = null;
}
}
}
} catch (HackAssertionException e) {
WXLogUtils.e("launchInspector HackAssertionException ", e);
}
}
}

In this way, You can control the debug mode flexibly.

No.3: Auto refresh page via ACTION_DEBUG_INSTANCE_REFRESH broadcast

ACTION_DEBUG_INSTANCE_REFRESH can be broadcast messages when the debug mode is switched or Chrome page refresh. You can use this mechanism to inform the current page to refresh in time.

public class RefreshBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (IWXDebugProxy.ACTION_DEBUG_INSTANCE_REFRESH.equals(intent.getAction())) {
if (mUri != null) {
if (TextUtils.equals(mUri.getScheme(), "http") || TextUtils.equals(mUri.getScheme(), "https")) {
loadWXfromService(mUri.toString());
} else {
loadWXfromLocal(true);
}
}
}
}
}

Example

The easiest way is reuse the code of playground. On the other hand QR code is not necessary, if you review the source code you can draw a conclusion that QR CODE is just a way to set devtools server address. There are two examples of how to open debug modes in the Playground App:

  • Set the debug mode via XXXApplication

    public class MyApplication extends Application {
    public void onCreate() {
    super.onCreate();
    initDebugEnvironment(true, "xxx.xxx.xxx.xxx"/*"DEBUG_SERVER_HOST"*/);
    }
    }
  • Set the debug mode by scan QR code

    You review the source code of playground.
