First, you have to create assets folder and copy your PDF into it.
Then you have to edit aaptOptions in build.gradle (Module: app), not to compass "pdf" file.
aaptOptions {
noCompress "pdf"
}
Layout file, refer to the example "Create PDF using PdfDocument".
MainActivity.java
package com.blogspot.android_er.androidpdf;
import android.content.res.AssetFileDescriptor;
import android.content.res.AssetManager;
import android.graphics.Bitmap;
import android.graphics.pdf.PdfRenderer;
import android.os.Bundle;
import android.os.ParcelFileDescriptor;
import android.support.v7.app.AppCompatActivity;
import android.widget.ImageView;
import android.widget.Toast;
import java.io.IOException;
public class MainActivity extends AppCompatActivity {
ImageView pdfView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pdfView = (ImageView)findViewById(R.id.pdfview);
try {
openPDF();
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(this,
"Something Wrong: " + e.toString(),
Toast.LENGTH_LONG).show();
}
}
private void openPDF() throws IOException {
//open file in assets
AssetManager assetManager = getAssets();
AssetFileDescriptor assetFileDescriptor =
assetManager.openFd("test.pdf");
ParcelFileDescriptor fileDescriptor =
assetFileDescriptor.getParcelFileDescriptor();
//open file from sdcard
/*
String targetPdf = "/sdcard/test.pdf";
File file = new File(targetPdf);
ParcelFileDescriptor fileDescriptor = null;
fileDescriptor = ParcelFileDescriptor.open(
file, ParcelFileDescriptor.MODE_READ_ONLY);
*/
//min. API Level 21
PdfRenderer pdfRenderer = null;
pdfRenderer = new PdfRenderer(fileDescriptor);
final int pageCount = pdfRenderer.getPageCount();
Toast.makeText(this,
"pageCount = " + pageCount,
Toast.LENGTH_LONG).show();
//Display page 0
PdfRenderer.Page rendererPage = pdfRenderer.openPage(1);
int rendererPageWidth = rendererPage.getWidth();
int rendererPageHeight = rendererPage.getHeight();
Bitmap bitmap = Bitmap.createBitmap(
rendererPageWidth,
rendererPageHeight,
Bitmap.Config.ARGB_8888);
rendererPage.render(bitmap, null, null,
PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY);
pdfView.setImageBitmap(bitmap);
rendererPage.close();
pdfRenderer.close();
assetFileDescriptor.close();
}
}
Remark: If you reported with the error "java.io.IOException: not create document. Error:", read next post.
