Hi,
I was trying to build my Qt widget app that is working on Android
since Qt 5.3, later 5.7 and 5.9
using downloaded offline Qt 5.11.2.
Using Qt JNI seems to be working properly, like:
RequestPermissions =
QAndroidJniObject("com/domain/myapp/permissions/RequestPermissions",
"(Landroid/app/Activity;)V",
QtAndroid::androidActivity().object<jobject>()
);
// Checking for errors in the JNI
QAndroidJniEnvironment env;
if (env->ExceptionCheck()) {
// Handle exception here.
env->ExceptionClear();
}
Unfortunately, the very first non-Qt JNI in my app crashes it.
JNIEnv* env;
if (g_javaVM->AttachCurrentThread(&env, NULL)<0)
{
return false;
}
jboolean res = env->CallStaticBooleanMethod(s_sharingClassID,
s_sharingMyFuncMethodID);
g_javaVM->DetachCurrentThread();
This is not something specific JNI, but really the first one non-Qt
JNI crashes it.
Is there any initialization or some magic in the new Qt JNI that could impact
non-Qt JNI?
Should I detach thread manually after Qt JNI?
