適配FileProvide需要宣告provider，編寫xml，以及在程式碼中做版本適配等…

可以抽取一個小庫簡化這些重複性操作，避免重複宣告provider，編寫xml，以及在程式碼中做版本適配…

使用

compile 'com.zhy.base:fileprovider:1.0.0'

通過FileProvider7這個類完成uri的獲取即可，例如：

FileProvider7.getUriForFile
FileProvider7.setIntentDataAndType
FileProvider7.setIntentData

示例一 拍照
private static final int REQUEST_CODE_TAKE_PHOTO = 0x110;
private String mCurrentPhotoPath;

public void takePhotoNoCompress(View view) {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        String filename = new SimpleDateFormat("yyyyMMdd-HHmmss", Locale.CHINA)
                .format(new Date()) + ".png";
        File file = new File(Environment.getExternalStorageDirectory(), filename);
        mCurrentPhotoPath = file.getAbsolutePath();
         // 僅需改變這一行
        Uri fileUri = FileProvider7.getUriForFile(this, file);

        takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
        startActivityForResult(takePictureIntent, REQUEST_CODE_TAKE_PHOTO);
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK && requestCode == REQUEST_CODE_TAKE_PHOTO) {
        mIvPhoto.setImageBitmap(BitmapFactory.decodeFile(mCurrentPhotoPath));
    }
    // else tip?

}
 

示例二 安裝apk

public void installApk(View view) {
    File file = new File(Environment.getExternalStorageDirectory(),
            "testandroid7-debug.apk");
    Intent intent = new Intent(Intent.ACTION_VIEW);
    // 僅需改變這一行
    FileProvider7.setIntentDataAndType(this,
            intent, "application/vnd.android.package-archive", file, true);
    startActivity(intent);
}
