APP版本更新(兼容6.0,7.0系统)
2024-05-27 10:16:49
本人不会写博客，就会代码。。。见谅
版本更新示例：
一。判断版本是否需要更新
int REQUEST_EXTERNAL_STORAGE = 1;
String[] PERMISSIONS_STORAGE = {Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE
};
int permission = ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
if (permission != PackageManager.PERMISSION_GRANTED) {// We don't have permission so prompt the user
ActivityCompat.requestPermissions(MainActivity.this,
PERMISSIONS_STORAGE,
REQUEST_EXTERNAL_STORAGE);
}
//判断返回的版本号与系统版本号是否一致 如果一直 UPDATA_NONEED 否则 UPDATA_CLIENT
if (versionResult.getVersionShort().equals(Tools.getVersion(MainActivity.this))) {Message msg = new Message();
msg.what = UPDATA_NONEED;
msg.obj="更新版本:"+versionResult.getVersionShort()+"\n"+"当前版本:"+Tools.getVersion(MainActivity.this);
mhHandler.sendMessage(msg);
} else {Message msg2 = new Message();
msg2.what = UPDATA_CLIENT;
JSONObject jsonObject=new JSONObject();
try {jsonObject.put("versionInfo","更新版本:"+versionResult.getVersionShort()+"\n"+"当前版本:"+Tools.getVersion(MainActivity.this));
jsonObject.put("intenturl",versionResult.getInstallUrl());
} catch (JSONException e) {e.printStackTrace();
}msg2.obj = jsonObject.toString();
mhHandler.sendMessage(msg2);
}
二、 mhHandler 设置
Handler mhHandler = new Handler() {public void handleMessage(android.os.Message msg) {switch (msg.what) {case UPDATA_NONEED:/**/
// Tools.showToast(MainActivity.this, getString(R.string.toast_3));
break;
case UPDATA_CLIENT:// 对话框通知用户升级程序
String updateInfo = msg.obj.toString();
try {JSONObject jsonObject=new JSONObject(updateInfo);
showUpdataDialog(jsonObject.getString("intenturl"),jsonObject.getString("versionInfo"));
} catch (JSONException e) {e.printStackTrace();
}break;
case GET_UNDATAINFO_ERROR:
// Tools.showToast(MainActivity.this, getString(R.string.toast_4));
break;
case DOWN_ERROR:String errormsg=msg.obj.toString();
Tools.showToast(MainActivity.this, getString(R.string.toast_4)+"错误信息:"+errormsg);
break;
}}};
三、showUpdataDialog 方法
/*
*
* 弹出对话框通知用户更新程序
*
* 弹出对话框的步骤： 1.创建alertDialog的builder. 2.要给builder设置属性, 对话框的内容,样式,按钮
* 3.通过builder 创建一个对话框 4.对话框show()出来
*/
protected void showUpdataDialog(final String fileurl,final String message) {AlertDialog.Builder builer = new AlertDialog.Builder(this);
builer.setTitle("版本升级");
builer.setMessage(message);
// builer.setMessage(getResources().getString(R.string.version_content));
// 当点确定按钮时从服务器上下载 新的apk 然后安装 װ
builer.setPositiveButton("确定", new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int which) {//System.out.println("下载更新apk");
downLoadApk(fileurl);
}});
builer.setNegativeButton("取消", null);
AlertDialog dialog = builer.create();
dialog.show();
}
四、downLoadApk方法
/*
* 从服务器中下载APK
*/
private final int UPDATA_NONEED = 100;// 版本号相同，不需要更新
private final int UPDATA_CLIENT = 200;// 版本不同，需要更新
private final int GET_UNDATAINFO_ERROR = 404;// 版本更新失败
private final int DOWN_ERROR = 300;// 下载失败
protected void downLoadApk(final String fileurl) {final ProgressDialog pd; // 进度条对话框
pd = new ProgressDialog(this);
pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pd.setMessage("正在下载更新");
pd.show();
new Thread() {@Override
public void run() {try {File file = DownLoadManager.getFileFromServer(fileurl, pd);
if (file!=null){sleep(3000);
installApkFile(file,"包名");
pd.dismiss(); // 结束掉进度条对话框
}else{Tools.showToast(MainActivity.this,"网络出错,请稍后再试");
pd.dismiss();
}} catch (Exception e) {Message msg = new Message();
msg.what = DOWN_ERROR;
msg.obj=e.getMessage();
mhHandler.sendMessage(msg);
e.printStackTrace();
}}}.start();
}
五、installApkFile 方法
private void installApkFile(File apkFille,String packagename){// 由于没有在Activity环境下启动Activity,设置下面的标签
if(Build.VERSION.SDK_INT>=24) {//判读版本是否在7.0以上
Uri apkUri = FileProvider.getUriForFile(this, packagename, apkFille);//在AndroidManifest中的android:authorities值
Intent install = new Intent(Intent.ACTION_VIEW);
install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
install.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);//添加这一句表示对目标应用临时授权该Uri所代表的文件
install.setDataAndType(apkUri, "application/vnd.android.package-archive");
startActivity(install);
} else{Intent install = new Intent(Intent.ACTION_VIEW);
install.setDataAndType(Uri.fromFile(apkFille), "application/vnd.android.package-archive");
install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(install);
}}
六、android 6.0之后动态权限
调用：
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {// 检查该权限是否已经获取
int i = ContextCompat.checkSelfPermission(this, permissions[0]);
int f = ContextCompat.checkSelfPermission(this, permissions[1]);
// 权限是否已经 授权 GRANTED---授权 DINIED---拒绝
if (i != PackageManager.PERMISSION_GRANTED) {// 如果没有授予该权限，就去提示用户请求
showDialogTipUserRequestPermission();
}else if(f!=PackageManager.PERMISSION_GRANTED){showDialogTipUserRequestPermissionf();
}
}
配置
private void showDialogTipUserRequestPermission() {new AlertDialog.Builder(this).setTitle("系统的服务信息权限不可用").setMessage("由于需要获取系统的服务信息，为你显示基站信息；\n否则，您将无法正常使用本程序").setPositiveButton("立即开启", new DialogInterface.OnClickListener() {@Override
public void onClick(DialogInterface dialog, int which) {startRequestPermission();
}}).setNegativeButton("取消", new DialogInterface.OnClickListener() {@Override
public void onClick(DialogInterface dialog, int which) {finish();
}}).setCancelable(false).show();
}
private void showDialogTipUserRequestPermissionf() {new AlertDialog.Builder(this).setTitle("sd卡储存权限不可用").setMessage("由于需要sd卡储存功能；\n否则，您将无法正常使用本程序").setPositiveButton("立即开启", new DialogInterface.OnClickListener() {@Override
public void onClick(DialogInterface dialog, int which) {startRequestPermission();
}}).setNegativeButton("取消", new DialogInterface.OnClickListener() {@Override
public void onClick(DialogInterface dialog, int which) {finish();
}}).setCancelable(false).show();
}// 开始提交请求权限
private void startRequestPermission() {ActivityCompat.requestPermissions(this, permissions, 321);
}// 用户权限 申请 的回调方法
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 321) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {if (grantResults[0] != PackageManager.PERMISSION_GRANTED) {// 判断用户是否 点击了不再提醒。(检测该权限是否还可以申请)
boolean b = shouldShowRequestPermissionRationale(permissions[0]);
if (!b) {// 用户还是想用我的 APP 的
// 提示用户去应用设置界面手动开启权限
showDialogTipUserGoToAppSettting();
} else
finish();
} else {Toast.makeText(this, "权限获取成功", Toast.LENGTH_SHORT).show();
}}}
}// 提示用户去应用设置界面手动开启权限
private void showDialogTipUserGoToAppSettting() {dialog = new AlertDialog.Builder(this).setTitle("系统的服务信息权限不可用").setMessage("请在-应用设置-权限-中，允许使用系统的服务信息权限").setPositiveButton("立即开启", new DialogInterface.OnClickListener() {@Override
public void onClick(DialogInterface dialog, int which) {// 跳转到应用设置界面
goToAppSetting();
}}).setNegativeButton("取消", new DialogInterface.OnClickListener() {@Override
public void onClick(DialogInterface dialog, int which) {finish();
}}).setCancelable(false).show();
}// 跳转到当前应用的设置界面
private void goToAppSetting() {Intent intent = new Intent();
intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", getPackageName(), null);
intent.setData(uri);
startActivityForResult(intent, 123);
}@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 123) {if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {// 检查该权限是否已经获取
int i = ContextCompat.checkSelfPermission(this, permissions[0]);
// 权限是否已经 授权 GRANTED---授权 DINIED---拒绝
if (i != PackageManager.PERMISSION_GRANTED) {// 提示用户应该去应用设置界面手动开启权限
showDialogTipUserGoToAppSettting();
} else {if (dialog != null && dialog.isShowing()) {dialog.dismiss();
}Toast.makeText(this, "权限获取成功", Toast.LENGTH_SHORT).show();
}}}
