java.lang.RuntimeException: takePicture échoué dans lollipop et guimauve

Question

J'essaie de faire une application qui prend l'image avant puis l'image arrière sur une seule intention d'activité, mon code de caméra avant est la même que ci-dessous et fonctionne parfaitement bien, je appelle même une finition pour détruire la surface et à l'intérieur onSurfaceDestroy() j'appelle la méthode initBackCam() donnée ci-dessous qui fonctionne bien jusqu'à ce que onSurfaceChanged() à l'intérieur onSurfaceChanged() j'appelle pCamera.takePicture (null, mPictureCallback, mPictureCallback) qui lève l'exception takePicture Failed

note: Ce code fonctionne bien jusqu'à ce que KitKat il échoue dans sucettes et de guimauve

J'ai essayé de retarder entre caméra avant et arrière, j'ai essayé de mettre le code pour caméra arrière dans une activité différente encore il jette la même erreur, j'ai relâché la caméra et appel startPreview() avant de prendre la photo mais toujours la même erreur

je l'ai utilisé à la suite des autorisations

Answer 1

Essayez cette

Ajouter:

SurfaceTexture st = new SurfaceTexture(MODE_PRIVATE); 
pCamera.setPreviewTexture(st); 

avant:

pCamera.startPreview(); 

takePicture failed
