Reading a PDF file from an assets folder in an Android application involves some specific steps.
In the provided code, an issue arises with the file path specified for the "abc.pdf" file. The path used, "android.resource://com.project.datastructure/assets/abc.pdf," is incorrect.
To resolve this, follow these steps:
Here's the updated code with the necessary modifications:
<code class="java">public class SampleActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); CopyReadAssets(); } private void CopyReadAssets() { AssetManager assetManager = getAssets(); InputStream in = null; OutputStream out = null; File file = new File(getFilesDir(), "abc.pdf"); try { in = assetManager.open("abc.pdf"); out = openFileOutput(file.getName(), Context.MODE_WORLD_READABLE); copyFile(in, out); in.close(); in = null; out.flush(); out.close(); out = null; } catch (Exception e) { Log.e("tag", e.getMessage()); } Intent intent = new Intent(Intent.ACTION_VIEW); intent.setDataAndType( Uri.fromFile(file), "application/pdf"); startActivity(intent); } private void copyFile(InputStream in, OutputStream out) throws IOException { byte[] buffer = new byte[1024]; int read; while ((read = in.read(buffer)) != -1) { out.write(buffer, 0, read); } } }</code>
This updated code will correctly copy the "abc.pdf" file to the application's internal storage and use the correct file path to open the PDF in a third-party PDF viewer.
