View 1 Replies View RelatedAndroid :: Calling A Non-static Java Method From C
Dec 22, 2009In my Android app, I need to call a non static java method from C/C++. But i get a blunt crash when i do it using GetMethodID/CallVoidMethod()1 methods.
I have done like this:
1. Register the method using GetMethodID() as follows (mine is a cpp file): jmethodID xyz = (env)->GetMethodID( cls, "showxyz", "()V");
2. And I call this method as follows: env->CallVoidMethod(cls, xyz);
3. In java, my showxyz() is defined this way(this basically enables a button which was disabled) void showxyz() {findViewById(R.id.btnPass).setEnabled(true);}
And this crashes.
But I have been using this method of calling Java funcs from C using a set of GetStaticMethodID/CallStaticVoidMethod()(for nonstatic methods) and that works always.
But in this case, I have to call a non-static method and i get a crash.

public class MyClass{

//Constructor
public MyClass(Tile[][] tiles, int rows, int cols) {..........
At this point, any changes to the mTiles object are reflected back to the tiles object.

Android :: Use HTTP Post Method Or Simple Java Socket Program
Mar 20, 2010Could someone please suggest me a good/efficient way to communicate with the server. I could think of two options 1) Use http post methods to send data to a php script at the server which would later call the google api's written in another java program (jar)or use php to use google api's (if its possible) to find nearby restaurants and send the list back to client. 2) Use simple java socket programming. The server has a jar file that supports multi threading and it does the job of finding restaurants and sending the list.

General :: How To Hack Webkit Java Class Method
Apr 18, 2012I try to make android java app that uses webkit browser component but in slight different way. My primary goal is to modify the webkit WebViewCore java class method so my android application uses my own WebView which derived from modified WebViewCore and acts as I wish. The problel is that WebViewCore and entire bunch of related classes is not part of public SDK.
So far I tried:
- replaced android.jar from SDK in my project with "full" version (framework.jar)
- copied entire webkit java classes from Android OS to my project and modified the method as I need.
- included in lib/armeabi the libwebcore.so and libchrome_net.so (these I grabbed from rooted phone which I gonna to use for experiments)
- compiled and created apk file with libs included (in the code java layer calls my own libs using System.loadLibrary(..))
- application crashes on launch on device with:
Code:
