Question

下面是我正在尝试记录日志并将日志的txt文件附加到指定gmail的代码。它不断给我许可拒绝附件。查看图像以了解错误。

以下是权限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission
        android:name="android.permission.WRITE_EXTERNAL_STORAGE"
        tools:node="replace" />

从文件中发送邮件意图的代码。

Intent intent = new Intent(Intent.ACTION_SEND); // this will show no apps available


intent.setData(Uri.parse("mailto:"));
                intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"techsupport@someemail.com"});
                intent.putExtra(Intent.EXTRA_SUBJECT, "Drive Bug Report");
                intent.putExtra(Intent.EXTRA_TEXT, createReportABugBody());
                intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                intent.setType("text/plain");
                Uri fileUri = getSleepLogFileUri();
                intent.putExtra(Intent.EXTRA_STREAM, fileUri);
                Intent chooser=Intent.createChooser(intent, "Email via...");
    startActivityForResult(chooser,0);

写入文件的另一个函数：

private String createReportABugBody() {
        Drive driveSDK = DriveApplication.getDrive();
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("Diagnostics").append("\n");
        try{
            PackageInfo pInfo = getActivity().getPackageManager().getPackageInfo(getActivity().getPackageName(), 0);
            stringBuilder.append("Version: ").append(pInfo.versionName)
                    .append("(").append(pInfo.versionCode).append(")").append("\n");
        } catch (PackageManager.NameNotFoundException e){
            e.printStackTrace();
        }
        stringBuilder.append("SDK Version: ").append(driveSDK.getVersion()).append("\n");
        stringBuilder.append("Device Model: Brand: ").append(Build.MANUFACTURER).append(", Model: ")
                .append(Build.MODEL).append(", Product: ").append(Build.PRODUCT).append("\n");
        stringBuilder.append("Type: Android \n");
        stringBuilder.append("OS: ").append(Build.VERSION.RELEASE).append("\n");
        stringBuilder.append("RM25 version: ").append(driveSDK.getRm25Version()).append("\n");
        stringBuilder.append("Microphone enabled: ").append(
                ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.RECORD_AUDIO) == PackageManager.PERMISSION_GRANTED)
                .append("\n");
        stringBuilder.append("User ID: ").append(Preferences.getPreference(Constants.KEY_STRING_USER_EMAIL, getActivity(), ""));


        stringBuilder.append("\n\n\nSTART LOGS:\n");
        try {
            File sleepLog = new File(getContext().getFilesDir(), mFileName);
            //                                                                               Uri uri = getUriForFile(getContext(),FILE_PROVDER_AUTHORITY ,sleepLog);
//              intent.putExtra(Intent.EXTRA_STREAM, uri);
            BufferedReader br = new BufferedReader(new FileReader(sleepLog));
            String line;


            while ((line = br.readLine()) != null) {
                stringBuilder.append(line);
                stringBuilder.append('\n');
            }
            br.close();
        }
        catch (IOException e) {
            e.printStackTrace();
        }

        return stringBuilder.toString();
    }

获取文件

private Uri getSleepLogFileUri() {
        /*
            change intent to SENDTO from SEND.
            will get "permission denied" from OS when Gmail opens.
         */
        Uri uri=null;
        try {


        File filePath = new File(DriveApplication.getApplicationInstance().getFilesDir(), "logs");
        File file = new File(filePath, mFileName);
        //File file = new File(getContext().getFilesDir(), mFileName);
         uri= Uri.fromFile(file);////getUriForFile(getContext(), FILE_PROVDER_AUTHORITY, filelocation);//Uri.fromFile(sleepLogFile);//
        }catch (Exception e){
            e.printStackTrace();
        }
        return uri;
    }

Answer 1

首先，第三方应用无法访问您应用的getFilesDir()。

其次，您的应用应该在Android 7.0+上使用FileUriExposedException崩溃。

要解决这两个问题，请使用FileProvider为您的文件投放，并使用FileProvider.getUriForFile()在Uri中使用EXTRA_STREAM。
