I developed an android application where it activates the barcode reader to read product barcodes.
What I find strange is that when you turn on the scanner it changes the position to horizontal ie the scanner lies.
How do I leave his orientation upright without changing orientation?
Guidance is enforced by the Activity used to read the code.
In her statement, in Manifest.xml , android is used: screenOrientation=" sensorLandscape .
As this Activity is part of Zxing, you can not (and should not) change it.
Places the reader's activity into portrait.
android:screenOrientation="portrait"
