Android 7.0 自动安装APK及拍照崩溃问题

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();        }    }
