Open PDF in Nougat

I have a file path: file: ///storage/emulated/0/Android/data/rocks.v d . *****. development / files / financial results for the 1st quarter of 2017.pdf

this is the code:

Intent intent = new Intent(Intent.ACTION_VIEW);
    try {
        String newFilePath = filePath.replaceAll("%20", " ");
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
            intent.setDataAndType(Uri.parse(newFilePath), "application/pdf");
        } else {
            Uri uri = Uri.parse(newFilePath);
            File file = new File(uri.getPath());
            if (file.exists()){
                uri = FileProvider.getUriForFile(context, context.getPackageName() + ".provider", file);
                intent.setDataAndType(uri, "application/pdf");
                intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            }
        }

        intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        context.startActivity(intent);

      

My uri = content: //rocks.v d . *****. develop.provider / files / Android / data / rocks.v d . *****. development / files / 1Q% 202017% 20financial% 20results.pdf

Reading Pdf opens with unexpected error. What's wrong?

intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

      

This is where you remove all existing flags, especially yours FLAG_GRANT_READ_URI_PERMISSION

. As a result, your activity will not be able to access your content.



Switch from setFlags()

to addFlags()

.

opening it in Adobe pdf reader. If Adobe Reader is not installed I am redirected to google play.



 private void viewPdf(Uri file){
Intent intent;
intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(file, "application/pdf");
try{
startActivity(intent);
}catch(ActivityNotFoundException e){
AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
builder.setTitle("No Application Found");
builder.setMessage("Download from Android Market?");
builder.setPositiveButton("Yes, Please", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

Intent marketIntent = new Intent(Intent.ACTION_VIEW);
marketIntent.setData(Uri.parse("market://details?id=com.adobe.reader"));
startActivity(marketIntent);

}
});
builder.setNegativeButton("No, Thanks", null);
builder.create().show();

}

If you are using android-N (like API 24 above) Do this

try {
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    File f = new File(Your File Path);

    Uri uri = null;


    // So you have to use Provider
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        uri = FileProvider.getUriForFile(this,getApplicationContext().getPackageName() + ".provider", file);

        // Add in case of if We get Uri from fileProvider.
        intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    }else{
        uri = Uri.fromFile(f);
    }

    intent.setDataAndType(uri, "application/pdf");
    startActivity(intent);
} catch(Exeption e){
    e.printstacktrace();
}

      

You can also use this code above Lollipop.
