我正在尝试拍照并将照片发送到服务器，但此刻我没有进入onActivityResult并且不知道发生了什么
这是代码：
public void capturar(View view){
Intent intent = new Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA);
if (intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent,REQUEST_IMAGE_CAPTURE);
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
String encodedImage = encodeImage(imageBitmap);
Log.d("encoded",encodedImage);
sendImage(encodedImage);
}
}
我可以预览相机，但点击Android照片并没有点击活动结果上的Log.d，任何提示»？
logcat的：

答案 0 :(得分：0)
您在清单中缺少权限以访问相机硬件。添加：
<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.hardware.camera.autofocus" />
