场景:银行及政府自助签署授权书一体机上面,硬件交互以及和业务无关的功能单独在另个apk中实现,在业务apk中只处理业务 如下图:
1. 服务端apk生成自定义PDF
1.添加依赖
implementation 'com.itextpdf:itext7-core:7.1.13'
2.客户端链接服务及调用生成pdf接口
package com.zchd.sign.pdf.client import android.content.ComponentName import android.content.Intent import android.content.ServiceConnection import android.os.Bundle import android.os.Environment import android.os.IBinder import android.util.Log import android.widget.Button import android.widget.Toast import androidx.appcompat.app.AppCompatActivity import com.blankj.utilcode.util.PermissionUtils import com.zchd.sign.pdf.service.SignPdfAidlInterface import com.zchd.sign.pdf.service.SignPdfCallback import com.zchd.sign.pdf.service.SignPdfInfo class MainActivity : AppCompatActivity() { private var pdfAidlInterface: SignPdfAidlInterface? = null private val serviceConnection: ServiceConnection = object : ServiceConnection { override fun onServiceConnected(componentName: ComponentName, iBinder: IBinder) { pdfAidlInterface = SignPdfAidlInterface.Stub.asInterface(iBinder) Toast.makeText(this@MainActivity, "链接成功", Toast.LENGTH_LONG).show() } override fun onServiceDisconnected(componentName: ComponentName) { Toast.makeText(this@MainActivity, "链接失败", Toast.LENGTH_LONG).show() } } override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) if (!PermissionUtils.isGranted(*PermissionActivity.permissions.toTypedArray())) { startActivity( Intent(this, PermissionActivity::class.java).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK) ) } findViewById<Button>(R.id.btn_connect).setOnClickListener { val intent = Intent() intent.component = ComponentName("com.zchd.sign.pdf.service", "com.zchd.sign.pdf.service.SignPdfService" ) bindService(intent, serviceConnection, BIND_AUTO_CREATE) } findViewById<Button>(R.id.btn_preview).setOnClickListener { val signPdfInfo = SignPdfInfo( userName = "王天一", userCardType = "身份证", userIdCard = "524000000000000", houseRelation = "/", repName = "测试", repCardType = "身份证", repIdCard = "123456789", authRelation = "/", signPicPath = null, fingerPicPath = null, repSignPicPath = null, repFingerPicPath = null ) val sdCardPath = Environment.getExternalStorageDirectory().absolutePath val pdfPath = "${sdCardPath}/sign_pdf.pdf" pdfAidlInterface?.sign(signPdfInfo, pdfPath, object : SignPdfCallback.Stub() { override fun onSuccess(path: String?) { Toast.makeText(this@MainActivity, "服务端生成pdf成功", Toast.LENGTH_LONG).show() val intent = Intent(baseContext, WebViewActivity::class.java) intent.putExtra("path", path) startActivity(intent) } override fun onFail() { Toast.makeText(this@MainActivity, "服务端生成pdf失败", Toast.LENGTH_LONG).show() } }) } } }
3.安卓上实现PDF预览?PDF.js 中文文档
pdfjs编译完后放在安卓assets 通过webView加载支持在线和本地pdf地址
webView.loadUrl("file:///android_asset/index.html?${path}")
