问题描述
当我在Android Studio中开发一个android应用程序时，我给了READ_STORAGE，WRITE_STORAGE权限，但无法将pdf存储在android Q版本中，比Q版本小，它工作正常。
请帮我。我已经提到了代码。
@SuppressLint("StaticFieldLeak")
private class API_DownloadStateapi extends AsyncTask < String,Void,String > {
final String url;
API_DownloadStateapi(String url) {
this.url = url;
}
@Override
protected String doInBackground(String...params1) {
try {
JSONObject jsonObject_sendingparams = new JSONObject();
try {
jsonObject_sendingparams.put("accountNumber",str_acc_number);
jsonObject_sendingparams.put("cifNumber",str_cifnumber);
} catch(JSONException ignored) {
}
String str_jsonparams = String.valueOf(jsonObject_sendingparams.toString().replace("\\",""));
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new ByteArrayHttpMessageConverter());
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());
restTemplate.getMessageConverters().add(new ResourceHttpMessageConverter());
HttpHeaders headers = RestTemplateHeaders.createHttpHeaders("downloadStatement_MOB",ctx);
httpentity < String > entity = new httpentity < >(str_jsonparams,headers);
response = restTemplate.postForEntity(url,entity,byte[].class);
respo = new String(response.getBody());
} catch(Exception eek) {
}
return respo;
}
@Override
protected void onPostExecute(String str) {
CommonDialog.onProgressdismiss();
try {
InputStream input = new ByteArrayInputStream(response.getBody());
File path = new File(Environment.getExternalStorageDirectory() + "/Download");
photoName = "Statement.pdf";
int num = 0;
File file = new File(path,photoName);
while (file.exists()) {
num++;
photoName = "Statement(" + num + ").pdf";
file = new File(path,photoName);
}
bufferedoutputstream output = new bufferedoutputstream(new FileOutputStream(file));
byte data[] = new byte[1024];
long total = 0;
int count;
while ((count = input.read(data)) != -1) {
total += count;
output.write(data,count);
}
output.flush();
output.close();
input.close();
} catch(IOException ignored) {}
}
}
请帮助我解决此问题。这是路径：File path = new File(Environment.getExternalStorageDirectory() + "/Download");，但不能在Q版本中使用
