When I start the program and press pushButton2 it appears logindialog. When I enter something into it and press logindialog's button the program is dieing. If I comment in .pro file the cryptopp lines the program works properly. If I leave empty the lineEdit and push passwordButton of logindialog, it again ask me about password and I give blank, but again die - see the second log appears(notice the P1,P2,P3... in both logs). I took openssl from this link and criptopp from this. I think the problem is somewhere with cryptopp. How can I increase stack and heap size for qt android? I don't think this is the issue and have read something about "stack trace debuging" but don't know how to do it. Never mind, what could be the issue in this case?
After edition:
I have tested it on my android 4.1.2 device LG optimus L1 e410. No matter if I test it on AVD with android 23/14/18/16 -> it is failing. If cryptopp is commented all goes OK. log2 compile output is same as first one with difference in time only.
After edition 2:

See pushButton in mainwindow.cpp and commented thigs in mainwindow.h(they are not commented really).

You are manually loading libstlport_shared.so, I suppose it's because it is needed by libcryptopp.so.
By default Qt, uses a STL library (libgnustl_shared.so in my case, you can check this in your android-build\libs\armeabi-v7a folder after compilation) upon compilation and deployment. If your crypto library uses a different one (apparently libstlport_shared.so), loading it manually from the .pro file as you did (ANDROID_EXTRA_LIBS += , LIB +=) will make the libcryptopp.so loadable, but you'll most likely get a seg fault whenever you'll pass a STL object (std::string for instance) from your code to a crypto function.
Two environments (your code and crypto one) are not using the same STL implementation, so they cannot safely send any STL object to each other without a serious potential segmentation fault (as one will consider objects as created from its own implementation when it was actually created with the other one: objects will most likely have different attributes....it's like forcing a cast between two completely different types).
You can verify this like that:
void MainWindow::on_pushButton_clicked()
{
byte ivec[16];
byte salt[32];
qDebug() << "Calling OS_GenerateRandomBlock";
CryptoPP::OS_GenerateRandomBlock(false, salt, sizeof(salt));
qDebug() << "Calling OS_GenerateRandomBlock";
CryptoPP::OS_GenerateRandomBlock(false, ivec, sizeof(ivec));
std::string v;
qDebug() << "Passing std::string to CryptoPP::StringSink";
CryptoPP::StringSink* sink = new CryptoPP::StringSink(v);
qDebug() << "Creating HexEncoder";
CryptoPP::HexEncoder hex( sink );
hex.Put(salt, sizeof(salt));
hex.MessageEnd();
QMessageBox::about(this,tr("Test1"),tr(v.c_str()));
QMessageBox::about(this,tr("Test1"),tr("XXX"));
}
Please confirm, but I'm pretty sure you'll see "Passing std::string to CryptoPP::StringSink" but not "Creating HexEncoder".
You should recompile libcryptopp.so to have it use the same STL implmentation as your main program (and cross your finger that the lib will work with that STL implementation).
