And i have placed all my .Jar files in libs folder
i removed jars in the Project > Properties > Java Build Path .
But still i get this crash . Also i am getting crash in setContentView in onCreate method . Why do i get this crash in one particular activity , while other activities are running . Moreover i have blocked all my codes in that activity ( code is as below )
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.myactivity);
}
Any related answers are welcomed and thanks in Advance .
Did you mark the checkboxes for required libraries in order and export tab
look at this Post
With SDK update to v22, the android dependencies and the android private libraries (v4, v7) are seperated into two different paths.
Make sure that all the libraries(of the main project) and the main project has "Android Private Libraries"(android cores) and the "Android Dependencies"(other libraries that particular project is dependent upon) is checked.
To do that, right click on the project, goto properties, select "Java Build Path" from the left panel, and in "Order and Export" tab, select the two.
thank you
