Android 调用拍照、相册、裁剪兼容8.0以上的二种方式

这段代码展示了在Android应用中如何调用相机和相册选择图片，然后进行系统裁剪处理。针对华为和小米设备的兼容性问题进行了特殊处理，包括设置裁剪比例和处理圆形裁剪框。

第一种

	private String mPhotoPath;
    private File mPhotoFile;
    private Uri imageUri;

                feedbackImg.setImageBitmap(bitmap);
                Logger.d(TAG, "--------------bitmap------------" + bitmap);
                mFilePath = ImageUtils.saveBitmap(this, bitmap, App.getInstance().getImageCacheDir());
                delImg.setVisibility(View.VISIBLE);

    getFileUri(mPhotoFile);
    intentCamera.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
    intentCamera.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
    startActivityForResult(intentCamera, PHOTO_REQUEST_CAMERA);
}

 * 调用手机相册
 */

    Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(intent, PHOTO_REQUEST_GALLERY);
}


@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Logger.i(TAG, "onActivityResult requestCode：" + requestCode + "，resultCode：" + resultCode);
    if (requestCode == CHANGE_PHONE && resultCode == RESULT_OK) {
        mPresenter.getUserInfo(userId);
    }

}

/**

 */
private void startPhoneZoom(Uri uri) {
    mAvatarFile = new File(App.getInstance().getAppCacheDir(), UUID.randomUUID().toString() + ".jpg");//这个是创建一个截取后的图片路径和名称。
    try {
        if (mAvatarFile.exists()) {
            mAvatarFile.delete();
        }

    intent.putExtra("corp", "true");
    //是否压缩
    intent.putExtra("scale", true);

    if (android.os.Build.MODEL.contains("HUAWEI")
                || Build.MANUFACTURER.equals("HUAWEI")) {//华为机特殊处理，防止裁剪框为圆形
            intent.putExtra("aspectX", 9998);
