Open PDF in Android App

Question

I am working on an application where I need to open a pdf file on a device,

I really got code on the internet that is similar to most examples. But the fact is, I can’t open the file, and the control goes directly to the Exception part.

Here is the code below:

public class MyPDFDemo extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button OpenPDF = (Button) findViewById(R.id.button); OpenPDF.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { File pdfFile = new File("/sdcard/Determine_RGB_Codes_With_Powerpoint [PDF Library].pdf"); if(pdfFile.exists()) { Uri path = Uri.fromFile(pdfFile); Intent pdfIntent = new Intent(Intent.ACTION_VIEW); pdfIntent.setDataAndType(path, "application/pdf"); pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); try { startActivity(pdfIntent); } catch(ActivityNotFoundException e) { Toast.makeText(MyPDFDemo.this, "No Application available to view pdf", Toast.LENGTH_LONG).show(); } } } }); } 

When I run this code: I used to view "There is no application to view pdf." Can I view a pdf file for someone.

Answer 1

Since your catch block has an ActivityNotFoundException, this means that you do not have an activity / application that can read the application / pdf file format. Install any pdf viewer from the Android Market (recently release Adobe), or use the aforementioned open source viewer, and your problem will most likely be solved.

When you start working with your parameters, she searches for all applications / actions / intentions registered to open the pdf format. Since you do not have them on your device, you get an ActivityNotFoundException

Answer 2

Your code is right, I also used the same code to open the PDF file in the viewer.

Since you do not have a viewer installed on your device, therefore, it cannot be opened without any viewer.

You can install Adobe reader for Android.

I can not open the PDF file in the emulator, so I need to test it using my device.

Answer 3

First install the PDF reader on the device. than using this code to read a pdf file from internal memory.

  protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); final TextView tv = (TextView)findViewById(R.id.tv); Button bt=(Button)findViewById(R.id.openbtn); bt.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { File pdfFile = new File(Environment.getExternalStorageDirectory(),"Leave.pdf"); if(pdfFile.exists()) { Uri path = Uri.fromFile(pdfFile); Intent pdfIntent = new Intent(Intent.ACTION_VIEW); pdfIntent.setDataAndType(path, "application/pdf"); pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); try{ startActivity(pdfIntent); }catch(ActivityNotFoundException e){ tv.setText("No Application available to view PDF"); } } else { tv.setText("File not found"); } } }); 

}
