Thank you for your answer. But it does not really change anything.
I´ve changed manifest to
AddManifestText(<activity
android:theme="@style/AppTheme.NoActionBar"
android:name="com.edwardvanraak.materialbarcodescanner.MaterialBarcodeScannerActivity"
android:label="@string/library_name" >
</activity>)
In b4a i use a MaterialBarcodeScannerBuilder to build the MaterialBarcodeScanner object.
With the MaterialBarcodeScanner i then can start a barcodescan
Sub Button1_Click
Log("Button1 Click event fired")
scanner.startScan
End Sub
startScan in the wrapper is defined as
public void startScan(final BA ba){
getObject().startScan();
}
startScan in the MaterialBarcodeLibrary is defined as
public void startScan() {
EventBus.getDefault().register(this);
if (mMaterialBarcodeScannerBuilder.getActivity() == null) {
throw new RuntimeException(
"Could not start scan: Activity reference lost (please rebuild the MaterialBarcodeScanner before calling startScan)");
}
int mCameraPermission = ActivityCompat.checkSelfPermission(
mMaterialBarcodeScannerBuilder.getActivity(),
Manifest.permission.CAMERA);
if (mCameraPermission != PackageManager.PERMISSION_GRANTED) {
requestCameraPermission();
} else {
// Open activity
BA.Log("EventBus.postSticky"); // Added to get more infos
EventBus.getDefault().postSticky(this);
BA.Log("Create intent"); // Added to get more infos
Intent intent = new Intent(mMaterialBarcodeScannerBuilder.getActivity(), MaterialBarcodeScannerActivity.class);
BA.Log("startActivity"); // Added to get more infos
mMaterialBarcodeScannerBuilder.getActivity().startActivity(intent);
}
}
BA.Log("EventBus.postSticky");
EventBus.getDefault().postSticky(this);
BA.Log("Create intent");
Intent intent = new Intent(mMaterialBarcodeScannerBuilder.getActivity(), MaterialBarcodeScannerActivity.class);
BA.Log("startActivity");
mMaterialBarcodeScannerBuilder.getActivity().startActivity(intent);
when i pres the button in my app at the end the startScan method in MaterialBarcodeScanner.java is called. The result is then the same same error as before
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
Button1 Click event fired
