안드로이드 운영체제 버전이 올라가니 새로운 오류들이 나타난다.

파일에 대한 URI정보를 가져오는 부분에서는 문제가 없다.

//백업파일 첨부
ContextWrapper cw = new ContextWrapper(SettingActivity.this);
//if (sd.canRead()){
File backupedDB = new File(cw.getDir(BACKUP_PATH, Context.MODE_PRIVATE), BAK_FILE_NAME);

Uri uri = null;
try {
    if (FileUtil.backUpExists(SettingActivity.this)) {
//                    if (Build.VERSION.SDK_INT > Build.VERSION_CODES.M) {
//                        uri = FileProvider.getUriForFile(SettingActivity.this, "com.test.fileprovider", backupedDB);
//                    } else {
//                        uri = Uri.fromFile(backupedDB);
//                    }
        uri = FileProvider.getUriForFile(SettingActivity.this, "com.test.fileprovider", backupedDB);  //안드로이드 5.0 버전도 이걸로 해야 된다.
        Log.i("test", "########### uri :  " + uri.toString());
    } else {
        Toast.makeText(SettingActivity.this, getResources().getString(R.string.setting_37), Toast.LENGTH_LONG).show();
        return;
    }

}catch (Exception e){
    e.printStackTrace();

이메일 발송하기 위해 첨부 할때 권한 오류가 발생한다.

Intent targetedShareIntent = new Intent(android.content.Intent.ACTION_SEND
targetedShareIntent.putExtra(Intent.EXTRA_STREAM, uri); // the attachment

아래와 같이 권한을 부여했음에도 오류가 발생한다.

getApplicationContext().grantUriPermission("com.google.android.gm", uri, Intent.FLAG_GRANT_READ_URI_PERMISSION);
grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);

 

 

오류해결을 위해 아래와 같이 추가해주었지만 해결되지 않았다.

targetedShareIntent.setClipData(ClipData.newRawUri("", uri));

 

오류는 발생하지만 이메일에 파일첨부는 제대로 동작한다.

그냥 이대로 쓸까???
