andjs
- support js engine quickjs and chromium v8
- native javascript object, such as jscrypto, adb
- multi-instance support
- inject java method by annotation
How to integrate andjs:
1: add andjs aar into your project
2: new AndJS(context) to create AndJS Instance
3: @CalledByJavascript to annotation your java method, which will be called in javascript
4: mJSInstance.injectObject to inject java object
5: mJSInstance.loadJSBuf(String jsbuf) to Run javascript
Sample code
import com.github.wuruxu.andjs.AndJS;
public class MainActivity extends AppCompatActivity {
private AndJS mJSInstance;
@Override
protected void onCreate(Bundle savedInstanceState) {
mJSInstance = new AndJS(this); //create AndJS Instance
obj = new MyObject();
//Inject java object into v8 engine as 'myobject'
mJSInstance.injectObject(obj, "myobject", null);
//Inject this Activity object into v8 engine as 'myactivity'
mJSInstance.injectObject(this, "myactivity", null);
String jsbuf = "myobject.doLog('This is a JS string');";
jsbuf += "var msg = myobject.getMessage(); adb.info(msg);";
jsbuf += "var home = myobject.getMyHome(); home.printRect(0, 0, 512, 512);";
jsbuf += "var homemsg = home.getMessage(); adb.info(homemsg);";
jsbuf += "var version = get_v8_version(); myactivity.updateTitle(version);";
mJSInstance.loadJSBuf(jsbuf); // Run Javascript in V8 engine
}
@CalledByJavascript
void updateTitle(String version) {
String str = getTitle().toString();
str += "@v8(" + version+")";
setTitle(str);
}
}
//sample code of MyObject
import com.github.wuruxu.andjs.CalledByJavascript;
public class MyObject extends Object {
private static final String TAG = "MyObject";
private MyHome home;
public MyObject() {
home = new MyHome();
}
@CalledByJavascript
public void doLog(String msg) {
Log.i(TAG, " * " + msg);
}
@CalledByJavascript
public String getMessage() {
return "This is a java string";
}
@CalledByJavascript
public MyHome getMyHome() {
return home;
}
}
//sample code of MyHome
import com.github.wuruxu.andjs.CalledByJavascript;
public class MyHome extends Object {
private static final String TAG = "MyHome";
public MyHome() {}
@CalledByJavascript
public void printRect(int x0, int y0, int x1, int y1) {
Log.i(TAG, " * x0 " + x0 + " y0 " + y0 + " x1 " + x1 + " y1 " + y1);
}
@CalledByJavascript
public String getMessage() {
return "This is a java string from MyHome";
}
}
