在nexus中使用安卓相机捕获图像后的空指针5
在我的应用程序中,我使用android设备相机捕捉我的图像。 在某些设备上它可以正常工作,但不是全部,我只是测试它LG的LG nexus 5 E960,在我捕捉到图像后,它总是会崩溃而无法保存结果,这是我的代码:
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 1);
protected void onActivityResult(int requestCode, int resultCode,
Intent returnimage) {
super.onActivityResult(requestCode, resultCode, returnimage);
switch (requestCode) {
case 1:
if (resultCode == RESULT_OK) {
Uri selectedImage = returnimage.getData();
String stringUri;
stringUri = selectedImage.toString();
Intent i1 = new Intent(MainActivity.this, Secondpage.class);
i1.putExtra("Stringuri",stringUri );
startActivity(i1);
}
break;
我的logcat是:
java.lang.RuntimeException: Failure delivering result ResultInfo{who=null,
request=1, result=-1, data=Intent { act=inline-data (has extras) }} to activity
{com.photostikers/com.photostikers.MainActivity}: java.lang.NullPointerException

使用像
@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");
Intent i1 = new Intent(MainActivity.this, Secondpage.class);
i1.putExtra("bitmap",imageBitmap );
startActivity(i1);
}
}
并在Secondpage Activity
获得像这样的图像
Bitmap bitImage = getIntent().getParcelableExtra("bitmap");
your_image+_view.setImageBitmap(bitImage);
通过Android开发人员文档获取缩略图
它在nexus5中成为共同的问题。
取而代之的是:
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 1);
尝试这个:
Uri mPhotoUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
new ContentValues());
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mPhotoUri);
startActivityForResult(intent,CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE_CONTENT_RESOLVER);
