Mobile and Embedded

@citiustech I have the same problem, have you solved that？ Could you help me? Thanks in advance!

@cKol1313 Hi, I know that if you configure like this: "./configure -device linux-imx6-g++ -confirm-license -opensource -device-option CROSS_COMPILE=arm-linux-gnueabihf- -static -no-compile-examples -no-xcb -no-qml-debug -no-sql-sqlite -no-tslib -qreal float -prefix /usr", it works. However, it has no opengl es at all. If I want to hold the opengl feature, how should I do? Thanks in advance!

@MorganeJ Hi, I wonder how you can cross compile qt5 using a desktop-opengl? Should it be opengl es2? Cound the opengl edition you compiled work well on your embedded board? Thanks in advance!

Finally I followed the instructions described here: http://blog.lasconic.com/share-on-ios-and-android-using-qml/ Using part of the code available here: https://github.com/lasconic/ShareUtils-QML So, I could implement the "share" feature quickly and with no issues :)

Any update on this?

Wow you are right ! Now it works as expected ! Thank you so much, I've been looking for a solution for like a week !

@T_Eng Also to say that my GUI is Qt Quick Qml code and I am trying to fill a TextField qml type

You've already asked this question: Audio recording Depending on what device you are using to record the audio, you may be limited to your available codecs. AFAIK, Qt does not provide codecs, just an interface to access them. You'd have to encode in a format native to your hardware and convert after the fact, or find a third-party codec you can integrate with your application and post-process the recorded audio after the fact.

Yes, I'm pretty sure I called it on the correct library. Or at least I thought it is the correct library. I found it here. I hope I will have some time over the weekend to try to compile it myself.

@raven-worx: Thanks i reffered following link to solve this issue: http://stackoverflow.com/questions/2780102/open-another-application-from-your-own-intent Thanks all. Bahubali P S

So I just had a breakthrough, that resulted in the application showing up on my phone. After building the project in Qt, I go to the build directory in a command line prompt, and type: mingw32-make install INSTALL_ROOT=.\Deploy androiddeployqt --output .\Deploy --install --input android-libcalqlatr.so-deployment-settings.json And lo and behold, the application is installed on the device. Why doesn't Qt Creator do this automatically?

I think you either have some strange race condition, or the connection to the database is dropped/busy so the prepare and/or exec are lagging.

Hi, at the moment I'm using Qt c++ code and it works. Here's the example: void AndroidImagePicker::openPicker() { QAndroidJniObject Intent__ACTION_PICK = QAndroidJniObject::getStaticObjectField("android/content/Intent", "ACTION_PICK", "Ljava/lang/String;"); qDebug() << "AndroidImagePicker Intent__ACTION_PICK.isValid()=" << Intent__ACTION_PICK.isValid(); QAndroidJniObject EXTERNAL_CONTENT_URI= QAndroidJniObject::getStaticObjectField("android/provider/MediaStore$Images$Media", "EXTERNAL_CONTENT_URI", "Landroid/net/Uri;"); qDebug() << "AndroidImagePicker EXTERNAL_CONTENT_URI.isValid()=" << EXTERNAL_CONTENT_URI.isValid(); QAndroidJniObject intent=QAndroidJniObject("android/content/Intent", "(Ljava/lang/String;Landroid/net/Uri;)V", Intent__ACTION_PICK.object<jstring>(), EXTERNAL_CONTENT_URI.object<jobject>() ); qDebug() << "AndroidImagePicker intent.isValid()=" << intent.isValid(); QtAndroid::startActivity(intent, 101, this); } void AndroidImagePicker::handleActivityResult(int receiverRequestCode, int resultCode, const QAndroidJniObject &data) { jint RESULT_OK = QAndroidJniObject::getStaticField<jint>("android/app/Activity", "RESULT_OK"); if( receiverRequestCode == 101 && resultCode == RESULT_OK ) { QAndroidJniObject uri = data.callObjectMethod("getData", "()Landroid/net/Uri;"); qDebug("AndroidImagePicker uri = %s", qPrintable(uri.toString())); QAndroidJniObject dadosAndroid = QAndroidJniObject::getStaticObjectField("android/provider/MediaStore$MediaColumns", "DATA", "Ljava/lang/String;"); QAndroidJniEnvironment env; jobjectArray projecao = (jobjectArray)env->NewObjectArray(1, env->FindClass("java/lang/String"), NULL); jobject projacaoDadosAndroid = env->NewStringUTF(dadosAndroid.toString().toStdString().c_str()); env->SetObjectArrayElement(projecao, 0, projacaoDadosAndroid); QAndroidJniObject contentResolver = QtAndroid::androidActivity().callObjectMethod("getContentResolver", "()Landroid/content/ContentResolver;"); QAndroidJniObject nullObj; QAndroidJniObject cursor = contentResolver.callObjectMethod("query", "(Landroid/net/Uri;[Ljava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)Landroid/database/Cursor;", uri.object<jobject>(), projecao, nullObj.object<jstring>(), nullObj.object<jobjectArray>(), nullObj.object<jstring>()); qDebug() << "AndroidImagePicker cursor.isValid()=" << cursor.isValid(); jint columnIndex = cursor.callMethod<jint>("getColumnIndexOrThrow","(Ljava/lang/String;)I", dadosAndroid.object<jstring>()); qDebug() << "AndroidImagePicker column_index=" << columnIndex; cursor.callMethod<jboolean>("moveToFirst"); QAndroidJniObject path = cursor.callObjectMethod("getString", "(I)Ljava/lang/String;", columnIndex); qDebug() << "AndroidImagePicker path.isValid()=" << path.isValid(); QString imagePath = "file://" + path.toString(); qDebug() << "AndroidImagePicker path" << imagePath; cursor.callMethod<jboolean>("close"); emit imagePathRetrieved(imagePath); } else qWarning() << "AndroidImagePicker wrong path"; } #ifndef ANDROIDIMAGEPICKER_H #define ANDROIDIMAGEPICKER_H #include <QObject> #include <QtAndroidExtras> #include <QDebug> class AndroidImagePicker : public QObject, public QAndroidActivityResultReceiver { Q_OBJECT public: AndroidImagePicker(); void openPicker(); virtual void handleActivityResult(int receiverRequestCode, int resultCode, const QAndroidJniObject &data); signals: void imagePathRetrieved(QString imagePath); }; #endif // ANDROIDIMAGEPICKER_H
