我有一个库项目的 .apk 文件，现在我想在我的应用程序项目中使用该 .apk 文件（在 assets 文件夹中），并且在运行我的应用程序项目时，我想将一个 .sql 文件放入该 .apk 文件中我单击一个按钮，然后我想将该 .apk 与该 .sql 文件一起存储在外部 SD 卡中。有可能这样做吗？

我通过使用以下代码得到：

private void onGenButtonClickListener() {
    Button generatebutton = (Button) findViewById(R.id.sign_apk);

    generatebutton .setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            generateAPK();

        }

    });
}

private void generateAPK() {
    try {
        String generatedApkPath = GENERATE_APK_TO_DIRECTORY + apkname + ".apk";

        String signedApkPath = GENERATE_APK_TO_DIRECTORY + apkname + "-signed.apk";
        Log.i("Sign APK", "Going to create signed apk in:" + signedApkPath);

        ZipSigner zipSigner = null;
        zipSigner = new ZipSigner();

        zipSigner.setKeymode("testkey");

        zipSigner.signZip(generatedApkPath, signedApkPath);

        // After signing apk , delete unsigned apk
        new File(generatedApkPath).delete();

        Toast.makeText(getApplicationContext(),
                "'" + apkname + "-signed.apk' is generated at " + GENERATE_APK_TO_DIRECTORY, Toast.LENGTH_LONG)
                .show();

    } catch (Throwable t) {
        Log.e("Signing apk", "Error while signing apk to external directory", t);
        t.printStackTrace();
    }
}
