Error loading image : java.lang.UnsatisfiedLinkError: Native method not found: xxx.xxxxxxx.xxxx.emoji_widgets.AndroidUtilities.loadBitmap:(Ljava/lang/String;Landroid/graphics/Bitmap;IIII)V
Then you have to recompile the native library with your own package names in the function using NDK. See the source file here https://github.com/madhur/android-chat-starter/blob/master/app/jni/image.c
JNIEXPORT void Java_in_co_madhur_chatbubblesdemo_AndroidUtilities_blurBitmap(JNIEnv *env, jclass class, jobject bitmap, int radius) {
i changed my package name, but still same error.
E/NativeLoader.java: [initNativeLibs:203]NativeLoader : java.lang.UnsatisfiedLinkError: Couldn't load chat.4 from loader dalvik.system.PathClassLoader[dexPath=/data/app/com.projectm.mobi-1.apk,libraryPath=/data/app-lib/com.projectm.mobi-1]: findLibrary returned null
java.lang.UnsatisfiedLinkError: Native method not found: com.project.main.tabs.emojiwidgets.AndroidUtilities.loadBitmap:(Ljava/lang/String;Landroid/graphics/Bitmap;IIII)V
i have the same issue, how can i recompile? this is my new image.c:
