Examples with CopyInputStream com.keepassdroid.stream.CopyInputStream used on opensource projects

Example 1 with CopyInputStream

use of com.keepassdroid.stream.CopyInputStream in project KeePassDX by Kunzisoft.

the class Kdb4 method testSaving.

private void testSaving(String inputFile, String password, String outputFile) throws IOException, InvalidDBException, PwDbOutputException {
    Context ctx = getContext();
    AssetManager am = ctx.getAssets();
    InputStream is = am.open(inputFile, AssetManager.ACCESS_STREAMING);
    ImporterV4 importer = new ImporterV4();
    PwDatabaseV4 db = importer.openDatabase(is, password, null);
    is.close();
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    PwDbV4Output output = (PwDbV4Output) PwDbOutput.getInstance(db, bos);
    output.output();
    byte[] data = bos.toByteArray();
    FileOutputStream fos = new FileOutputStream(TestUtil.getSdPath(outputFile), false);
    InputStream bis = new ByteArrayInputStream(data);
    bis = new CopyInputStream(bis, fos);
    importer = new ImporterV4();
    db = importer.openDatabase(bis, password, null);
    bis.close();
    fos.close();
}

Example 2 with CopyInputStream

use of com.keepassdroid.stream.CopyInputStream in project KeePassDX by Kunzisoft.
