29830/com.example.hamza.weekendmessanger e/androidruntime: fatal exception: main java.lang.illegalstateexception: not execute method android:onclick
i think have add proper permission in
manifest
here are:
<uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.write_external_storage" /> <uses-permission android:name="android.permission.access_wifi_state" /> <uses-permission android:name="android.permission.change_wifi_state" /> <uses-permission android:name="android.permission.change_network_state" /> <uses-permission android:name="android.permission.access_network_state" />
