내부 저장소 읽기 쓰기

Question

setDestinationInExternalFilesDir (this, "/ download", "app-debug.apk"); 왜 이것이 내부 저장소에 저장됩니까?

및 /data/data/com.example.xxx/files/download/app-debug.apk

downloadManager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE); 
Uri uri = Uri.parse("http://"); 
DownloadManager.Request request = new DownloadManager.Request(uri); 
request.setDestinationInExternalFilesDir(this, "/download", "app-debug.apk"); 
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); 
Long reference = downloadManager.enqueue(request); 

File imagePath = new File(getFilesDir(), "download"); 
File newFile = new File(imagePath, "app-debug.apk"); 
CharSequence text1 = "no file"; 
Toast toast1 = Toast.makeText(getApplicationContext(), newFile.getAbsolutePath()+"can't find file ", Toast.LENGTH_SHORT); 

if(!newFile.exists()){toast1.show(); return false;} 
Uri uri2 = FileProvider.getUriForFile(this,"com.example.xxx",newFile); 
Intent i = new Intent(); 
i.setAction(android.content.Intent.ACTION_VIEW); 
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
i.setData(uri2); 
i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); 
i.setType("application/vnd.android.package-archive"); 
startActivity(i);

mby 내부 저장소 또는 sth에 외부 저장소가 있습니까?

Answer 1

getFilesDir()을 getExternalFilesDir()으로 바꿉니다.

그리고 공급자 경로를 수정하십시오. 당신이 원래 가진 것처럼.
