现在在一家外包公司，所以经常地接到一些不同的项目，基本上每个项目都需要用到版本升级，故在此总结一下版本升级的方法以及不同安卓版本的适配方法。
版本更新工具类：
public class AppDownloadManager {
public static final String TAG = "AppDownloadManager";
private String apkName = "newapk.apk";
private WeakReference<Activity> weakReference;
private DownloadManager mDownloadManager;
private DownloadChangeObserver mDownLoadChangeObserver;
private DownloadReceiver mDownloadReceiver;

private OnUpdateListener mUpdateListener;
private Context mContext;
private PopupWindow mPopupWindow;
private ProgressBar mProgress;
private Dialog downloadDialog;
public AppDownloadManager(Activity activity) {
mContext = activity;
weakReference = new WeakReference<Activity>(activity);
mDownloadManager = (DownloadManager) weakReference.get().getSystemService(Context.DOWNLOAD_SERVICE);
mDownLoadChangeObserver = new DownloadChangeObserver(new Handler());
mDownloadReceiver = new DownloadReceiver();
}
//版本更新弹窗
public void showNoticeDialog(final String apkUrl, final String title, final String des) {
View view = View.inflate(mContext, R.layout.sys_pop_version_update, null);
TextView tvVersionDes = view.findViewById(R.id.tvVersionDes);//描述
TextView tvSure = view.findViewById(R.id.tvSure);//确定
TextView tvCancle = view.findViewById(R.id.tvCancle);//取消
tvVersionDes.setText(des);
tvSure.setOnClickListener(v -> {
mPopupWindow.dismiss();
downloadApk(apkUrl,title,des);
// showDownloadDialog(apkUrl,title,des);
});
tvCancle.setOnClickListener(v -> mPopupWindow.dismiss());
mPopupWindow = PopWindowUtil.getInstance()
.makePopupWindow(mContext, view, ViewGroup.LayoutParams.MATCH_PARENT,true)
.showLocation(mContext, view, Gravity.CENTER, 0, 0,0);
}
public void setUpdateListener(OnUpdateListener mUpdateListener) {
this.mUpdateListener = mUpdateListener;
}
public void downloadApk(String apkUrl, String title, String desc) {
//三个参数分别对应：APK的下载路径，更新弹窗的标题，更新弹窗的内容（一般放版本的更新内容）
// 在下载之前应该删除已有文件
File apkFile = new File(weakReference.get().getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS), apkName);
if (apkFile != null && apkFile.exists()) {
apkFile.delete();
}

//设置title

// 完成后显示通知栏

mDownLoadChangeObserver);
// 注册广播，监听APK是否下载完成
weakReference.get().registerReceiver(mDownloadReceiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
}
/**
* 对应{@link Activity()} ()}
*/
public void onPause() {
weakReference.get().getContentResolver().unregisterContentObserver(mDownLoadChangeObserver);
weakReference.get().unregisterReceiver(mDownloadReceiver);
}
private void updateView() {
int[] bytesAndStatus = new int[]{0, 0, 0};
DownloadManager.Query query = new DownloadManager.Query().setFilterById(mReqId);
Cursor c = null;
try {
c = mDownloadManager.query(query);
if (c != null && c.moveToFirst()) {
//已经下载的字节数
bytesAndStatus[0] = c.getInt(c.getColumnIndexOrThrow(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR));
//总需下载的字节数
bytesAndStatus[1] = c.getInt(c.getColumnIndexOrThrow(DownloadManager.COLUMN_TOTAL_SIZE_BYTES));
//状态所在的列索引
bytesAndStatus[2] = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS));
}
} finally {
if (c != null) {
c.close();
}
}
if (mUpdateListener != null) {
mUpdateListener.update(bytesAndStatus[0], bytesAndStatus[1]);
}
Log.i(TAG, "下载进度：" + bytesAndStatus[0] + "/" + bytesAndStatus[1] + "");
}

public DownloadChangeObserver(Handler handler) {
super(handler);

@Override

super.onChange(selfChange);
updateView();
}
}
//监听下载状态
class DownloadReceiver extends BroadcastReceiver {
@Override
public void onReceive(final Context context, final Intent intent) {
boolean haveInstallPermission;
// 兼容Android 8.0
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
//先获取是否有安装未知来源应用的权限

public interface OnUpdateListener {
void update(int currentByte, int totalByte);
}
public interface AndroidOInstallPermissionListener {

}
在下载好APK后，安卓8.0的手机需要检查APP是否拥有安装未知来源应用的权限，检查权限的工具类（提示：该工具类因为是继承FragmentActivity，所以需要在AndroidManifest中声明该Activity）：
public class AndroidOPermissionActivity extends FragmentActivity {
public static final int INSTALL_PACKAGES_REQUESTCODE = 1;
private AlertDialog mAlertDialog;
public static AppDownloadManager.AndroidOInstallPermissionListener sListener;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// 弹窗提示，跟用户说明是为了升级我们的APP所以需要获得安装未知来源的权限
if (Build.VERSION.SDK_INT >= 26) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.REQUEST_INSTALL_PACKAGES}, INSTALL_PACKAGES_REQUESTCODE);
} else {
finish();
}
}
@RequiresApi(api = Build.VERSION_CODES.O)
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case INSTALL_PACKAGES_REQUESTCODE:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
if (sListener != null) {
sListener.permissionSuccess();
finish();
}
} else {
//startInstallPermissionSettingActivity();
showDialog();
}
break;
}
}
private void showDialog() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(R.string.app_name);
builder.setMessage(R.string.sys_apply_permission);
builder.setPositiveButton(R.string.sys_ensure, new DialogInterface.OnClickListener() {
@RequiresApi(api = Build.VERSION_CODES.O)
@Override
public void onClick(DialogInterface dialogInterface, int i) {
startInstallPermissionSettingActivity();
mAlertDialog.dismiss();
}
});
builder.setNegativeButton(R.string.sys_cancel, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
if (sListener != null) {
sListener.permissionFail();
}
mAlertDialog.dismiss();
finish();
}
});
mAlertDialog = builder.create();
mAlertDialog.show();
}
@RequiresApi(api = Build.VERSION_CODES.O)
private void startInstallPermissionSettingActivity() {
//注意这个是8.0新API
Intent intent = new Intent(Settings.ACTION_MANAGE_UNKNOWN_APP_SOURCES, Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, 1);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1 && resultCode == RESULT_OK) {
// 授权成功
if (sListener != null) {
sListener.permissionSuccess();
}
} else {
// 授权失败
if (sListener != null) {
sListener.permissionFail();
}
}
finish();
}
@Override
protected void onDestroy() {
super.onDestroy();
sListener = null;
}
}
在获取安装权限之后，需要打开APK，即下载工具类的installApk()方法。在安卓7.0以后，需要配置provider来获取APK的位置并打开安装。
uri = FileProvider.getUriForFile(context,
context.getPackageName() + ".fileProvider",
new File(context.getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS), apkName));
配置FileProvider步骤如下：首先在AndroidManifest中声明Provider
<application
…
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.fileProvider"
android:grantUriPermissions="true"
android:exported="false">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/update_files" />
</provider>
…
</application>
其次在res文件夹下创建 xml文件，并创建update_files.xml:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<!--文件权限配置-->
<!--1、对应内部内存卡根目录：Context.getFileDir()-->
<files-path
name="root"
path="/" />
<!--2、对应应用默认缓存根目录：Context.getCacheDir()-->
<cache-path
name="cache"
path="/" />
<!--3、对应外部内存卡根目录：Environment.getExternalStorageDirectory()-->
<external-path
name="path"
path="/" />
<external-path
name="ext_root"
path="pictures/" />
<!--4、对应外部内存卡根目录下的APP公共目录：Context.getExternalFileDir(String)-->
<external-files-path
name="ext_pub"
path="/" />
<!--5、对应外部内存卡根目录下的APP缓存目录：Context.getExternalCacheDir()-->
<external-cache-path
name="ext_cache"
path="/" />
</paths>
以上，就完成了版本自动升级工具的封装。在Activity中，只要创建AppDownloadManager实例对象，并调用该对象的showNoticeDialog方法，即可完成版本的自动升级。附上版本升级弹窗的xml：
<?xml version="1.0" encoding="utf-8"?>
