解决方法
1，在AndroidManifest中添加
<provider android:name="android.support.v4.content.FileProvider" android:authorities="${applicationId}.fileProvider" android:grantUriPermissions="true" android:exported="false"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths" /> provider>2，在res目录下新建xml文件夹，添加file_paths.xml文件，内容如下：
<?xml version="1.0" encoding="utf-8"?> <paths> <external-path path="Android/data/com.heyikun.hehemall/" name="files_root" /> <external-path path="." name="external_storage_root" /> <external-path name="external_storage_root" path="."/> <files-path name="files" path="."/> paths>3，安装APP
private void installApk(File file) { Intent install = new Intent(Intent.ACTION_VIEW); //判断是否是AndroidN以及更高的版本 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { install.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); Uri contentUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".fileProvider", file); install.setDataAndType(contentUri, "application/vnd.android.package-archive"); } else { install.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive"); install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); } mContext.startActivity(install); }4，拍照
public Intent dispatchTakePictureIntent() throws IOException { Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); if (takePictureIntent.resolveActivity(mContext.getPackageManager()) != null) { File file = createImageFile(); Uri photoFile; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { String authority = mContext.getApplicationInfo().packageName + ".fileProvider"; photoFile = FileProvider.getUriForFile(this.mContext.getApplicationContext(), authority, file); } else { photoFile = Uri.fromFile(file); } if (photoFile != null) { takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoFile); } } return takePictureIntent; } private void openCamera() { try { Intent intent = captureManager.dispatchTakePictureIntent(); startActivityForResult(intent, ImageCaptureManager.REQUEST_TAKE_PHOTO); } catch (IOException e) { e.printStackTrace(); } catch (ActivityNotFoundException e) { // TODO No Activity Found to handle Intent e.printStackTrace(); } }更多相关文章
