ARMAssembler generated scanline__

I normolly get the message
generated scanline__00000077:03515104_00000000_00000000 [ 33 ipp] (47 ins) at [0x388750:0x38880c] in 712163 ns in logcat view, android.

 While searching for ARMAssembler generated scanline__ on google I got the following results referring to scanline.cpp.
http://source-android.frandroid.com/system/core/libpixelflinger/scanline.cpp
or
http://gitorious.org/android-enablement/system-core/blobs/6090dacd1894429baaf13f7b30b2f6e9e2c1617f/libpixelflinger/scanline.cpp

...but no explicit binding was found.

PROBLEM
The following +GWT error was giving me pain.
"Binding requested for constant key Key[type=java.lang.String, annotation=[none]] but no explicit binding was found."

 SOLUTION
I searched through Google, but worthless. After 24 hours, what i found was, in the constructor for View which was being @injected had an argument of type java.lang.String causing the error.


@Inject
public MyDetailsView(String fname) {
widget = (uiBinder.createAndBindUi(this));
}

Just after removing the argument of type java.lang.String, it worked brilliant.

 MORE...
Similar error occurs when Constructor is @Injected on GWT Presenter with a argument but not supplying the arguement.
eg. 

@Inject
public SearchTransactionPresenter(boolean autoBind, EventBus eventBus, ISearchTransactionView view, ISearchTransactionProxyPlace proxy) {
super(autoBind, eventBus, view, proxy);
getView().setUiHandlers(this);
}

 Primitive type boolean autoBind must be explicitly bound in GinModule.
REFERENCES

Same sort of error are posted here : how to diagnose "but no explicit binding was found" compiler error?
