Quick Start

After completing integration, you can launch a complete PDF document interface via CPDFDocumentActivity or CPDFDocumentFragment. UI and feature behavior are controlled through CPDFConfiguration, with the default configuration file being tools_default_configuration.json.

Storage Access Notes (Android 10/11+)

• It is recommended to use Uri (SAF / MediaStore) to open and save documents.
• Using file paths directly may be restricted by Scoped Storage on newer systems.
• tools_default_configuration.json is packaged in the Tools module assets by default and can be used directly or copied to your app's assets directory to override.

Using CPDFDocumentActivity

CPDFDocumentActivity is a ready-to-use full-screen PDF document Activity.

Open via Uri

java

Intent intent = new Intent(context, CPDFDocumentActivity.class);
intent.setData(uri); // Uri returned from SAF picker
intent.putExtra(CPDFDocumentActivity.EXTRA_FILE_PASSWORD, password); // Can be null
CPDFConfiguration configuration = CPDFConfigurationUtils.normalConfig(
    context, "tools_default_configuration.json");
intent.putExtra(CPDFDocumentActivity.EXTRA_CONFIGURATION, configuration);
intent.putExtra(CPDFDocumentActivity.EXTRA_PAGE_INDEX, 0); // Default page index
context.startActivity(intent);

kotlin

val intent = Intent(context, CPDFDocumentActivity::class.java).apply {
    data = uri
    putExtra(CPDFDocumentActivity.EXTRA_FILE_PASSWORD, password)
    val configuration = CPDFConfigurationUtils.normalConfig(
        context, "tools_default_configuration.json")
    putExtra(CPDFDocumentActivity.EXTRA_CONFIGURATION, configuration)
    putExtra(CPDFDocumentActivity.EXTRA_PAGE_INDEX, 0)
}
context.startActivity(intent)

Open via File Path

java

Intent intent = new Intent(context, CPDFDocumentActivity.class);
intent.putExtra(CPDFDocumentActivity.EXTRA_FILE_PATH, filePath);
intent.putExtra(CPDFDocumentActivity.EXTRA_FILE_PASSWORD, password);
CPDFConfiguration configuration = CPDFConfigurationUtils.normalConfig(
    context, "tools_default_configuration.json");
intent.putExtra(CPDFDocumentActivity.EXTRA_CONFIGURATION, configuration);
intent.putExtra(CPDFDocumentActivity.EXTRA_PAGE_INDEX, 0);
context.startActivity(intent);

kotlin

val intent = Intent(context, CPDFDocumentActivity::class.java).apply {
    putExtra(CPDFDocumentActivity.EXTRA_FILE_PATH, filePath)
    putExtra(CPDFDocumentActivity.EXTRA_FILE_PASSWORD, password)
    val configuration = CPDFConfigurationUtils.normalConfig(
        context, "tools_default_configuration.json")
    putExtra(CPDFDocumentActivity.EXTRA_CONFIGURATION, configuration)
    putExtra(CPDFDocumentActivity.EXTRA_PAGE_INDEX, 0)
}
context.startActivity(intent)

Supported Intent Parameters

Extra Constant	Type	Description
EXTRA_FILE_PATH	String	Absolute path to the PDF file
EXTRA_FILE_URI	Uri (via setData())	SAF / MediaStore Uri
EXTRA_FILE_PASSWORD	String	Document password, can be null
EXTRA_CONFIGURATION	CPDFConfiguration	UI and feature configuration object
EXTRA_PAGE_INDEX	int	Default page index to display on open (0-based)

Using CPDFDocumentFragment

CPDFDocumentFragment can be embedded in any Activity for more flexible interface customization.

Basic Usage

java

CPDFConfiguration configuration = CPDFConfigurationUtils.normalConfig(
    context, "tools_default_configuration.json");
CPDFDocumentFragment documentFragment = CPDFDocumentFragment.newInstance(
    uri, "password", configuration);
getSupportFragmentManager()
    .beginTransaction()
    .replace(R.id.fragment_container_view, documentFragment, "documentFragment")
    .commit();

kotlin

val configuration = CPDFConfigurationUtils.normalConfig(
    context, "tools_default_configuration.json")
val documentFragment = CPDFDocumentFragment.newInstance(
    uri, "password", configuration)
supportFragmentManager
    .beginTransaction()
    .replace(R.id.fragment_container_view, documentFragment, "documentFragment")
    .commit()

Factory Methods

CPDFDocumentFragment provides the following static methods for creating instances:

Method	Description
newInstance(String filePath, String password, CPDFConfiguration config)	Create via file path
newInstance(Uri uri, String password, CPDFConfiguration config)	Create via Uri
newInstance(Bundle bundle)	Create via Bundle (advanced usage)

Initialization Callback

Use setInitListener() to listen for the Fragment initialization completion event and obtain the CPDFViewCtrl instance:

java

documentFragment.setInitListener(pdfView -> {
    // pdfView is ready, perform further operations
    // e.g.: pdfView.getCPdfReaderView().setDisplayMode(...)
});

kotlin

documentFragment.setInitListener { pdfView ->
    // pdfView is ready
}
