Hi,

What version of Qt ?
What version of Android ?
Got any error message ?
Got any warning ?

[Bhushan_Sure]

@SGaist Thank you for reply, i solved the error , if anybody needs code ping me :)

[SGaist]

What was the error ?

[dheerendra]

@Bhushan_Sure you better post the details on how did you resolve the issue. Posting the code should help with example.

[Bhushan_Sure]

@dheerendra @SGaist Hello, The code is absouletly fine, the error was in the "package specifying " in manifest.xml and in ".java" file, it was not matching, we have to make sure that package name should be same everywhere.

[dheerendra]

Just show those entries here with example in manifest and package & what should be matching will help. It helps the community.

[Bhushan_Sure]

Okay Sir @dheerendra

Manifest.xml

<manifest package="com.amin.QtAndroidToastJava">

Qtandroidtoast.java

package com.amin.QtAndroidToastJava;

Notificationclient.cpp

QAndroidJniObject::callStaticMethod<void>("com/amin/QtAndroidToastJava/QtAndroidToastJava",
                                       "makeText",
                                       "(Ljava/lang/String;)V",
                                       javaNotification.object<jstring>());

these files should have same name while including in Qt project
(1) In manifest.xml ,package name.
(2) In java file we have to include Package name .
(3) Also while calling java function from C++ we have to specify same package details, as specify in parameters of function.

Above things should be same or it will lead error.
