Import PDF from adobe

Question

I am looking to do the following in andriod studio

1. User will open his mail client and click preview on a PDF. It opens the file in adobe reader.

2. The user makes comments in adobe and when done press share

3. My andriod app is shown and the users selects my app

4. My andriod app gets the pdf and saves it externally to my server.

I have part 1,2,3 so far but not 4,5. Its my understanding that you can not access applications storage, but a poster posted this, but I am unsure on how to use that?

Answer 1

In order to get the PDF you'll need to create an activity for this use case that listens for those "sharing" intents.

ShareActivity.java

void onCreate (Bundle savedInstanceState) {

    // Get intent, action and MIME type
    Intent intent = getIntent();
    String action = intent.getAction();
    String type = intent.getType();

    if (Intent.ACTION_SEND.equals(action) && type != null) {
        if ("application/pdf".equals(type)) {
            handlePDF(intent);
        } 
    } else if (Intent.ACTION_SEND_MULTIPLE.equals(action) && type != null) {
        if (type.startsWith("application/pdf")) {
           // Handle multiple pdfs being sent
        }
    } else {
        // Handle other intents, such as being started from the home screen
    }
}


void handlePDF(Intent intent) {
    Uri pdfUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
    if (pdfUri != null) {

        // TODO: Use your server-side here to save. 

    }
}

And then add this to your AndroidManifest.xml so Android knows what activity to get when they select your application to share to:

<activity android:name=".ui.ShareActivity" >
    <intent-filter>
        <action android:name="android.intent.action.SEND" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:mimeType="application/pdf" />
    </intent-filter>
</activity>

public class savepdf extends ActionBarActivity {
    static final int REQUEST_IMAGE_OPEN = 1;
    private static final int WRITE_REQUEST_CODE = 43;
    private Uri mData;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_savepdf);

        // Get intent, action and MIME type
        Intent intent = getIntent();
        String action = intent.getAction();
        String type = intent.getType();

        if (Intent.ACTION_SEND.equals(action) && type != null) {
            if ("application/pdf".equals(type)) {
                handlePDF(intent);
            }
        } else if (Intent.ACTION_SEND_MULTIPLE.equals(action) && type != null) {
            if (type.startsWith("application/pdf")) {
                // Handle multiple pdfs being sent
            }
        } else {
            // Handle other intents, such as being started from the home screen
        }
    }

    void handlePDF(Intent intent) {
        Uri pdfUri = (Uri) intent.getParcelableExtra(Intent.EXTRA_STREAM);
        if (pdfUri != null) {
            //savefile(pdfUri);

            String sourceFilename= pdfUri.getPath();
            String destinationFilename = android.os.Environment.getExternalStorageDirectory().getPath()+File.separatorChar+"abc.pdf";

            BufferedInputStream bis = null;
            BufferedOutputStream bos = null;

            try {
                bis = new BufferedInputStream(new FileInputStream(sourceFilename));
                bos = new BufferedOutputStream(new FileOutputStream(destinationFilename, false));
                byte[] buf = new byte[1024];
                bis.read(buf);
                do {
                    bos.write(buf);
                } while(bis.read(buf) != -1);
            } catch (IOException e) {

            } finally {
                try {
                    if (bis != null) bis.close();
                    if (bos != null) bos.close();
                } catch (IOException e) {

                }
            }
