Android动态获取系统权限+调⽤外部应⽤读取本地⽂件（TBS+⾃定义）⼀、获取动态权限
1.创建Android应⽤，在配置⽂件中添加临时访问⽂件权限
<!-- android 7.0临时赋予访问权限 android:name="android.t.FileProvider" -->
<provider
android:name="t.FileProvider"
android:authorities="ample.build_input"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths"/>
</provider>
新建xml⽂件，配置name和path路径
<?xml version="1.0" encoding="utf-8"?>
<paths>
<!-- name随便起-->
<external-path
name="camera_photos"
path="/"/>
</paths>
2.配置系统需要⽤到的系统权限
<!-- 向SD卡写⼊数据权限 -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission
android:name="android.permission.WRITE_SETTINGS"
tools:ignore="ProtectedPermissions"/>
3.编写申请动态权限⽅法，在onCreate()⽅法中调⽤
//申请权限
private boolean getPermission(Activity activity){
boolean rs=false;
// 声明⼀个集合，在后⾯的代码中⽤来存储⽤户拒绝授权的权
List<String> permissionList = new ArrayList<>();
String[] permissions = new String[]{
Manifest.permission.READ_EXTERNAL_STORAGE,//读取内存卡
Manifest.permission.WRITE_EXTERNAL_STORAGE,//写⼊内存卡
//                Manifest.permission.MOUNT_UNMOUNT_FILESYSTEMS,//允许挂载和反挂载⽂件系统可移动存储
//                Manifest.permission.READ_PHONE_STATE,//读取⼿机状态和⾝份
/* Manifest.permission.ACCESS_WIFI_STATE,//获取使⽤Wi-Fi等WLAN⽆线⽹络
Manifest.permission.CHANGE_WIFI_STATE,//允许程序改变Wi-Fi连接状态
Manifest.permission.ACCESS_NETWORK_STATE,//允许程序访问有关GSM⽹络信息
Manifest.permission.CHANGE_NETWORK_STATE,//允许程序改变⽹络连接状态
Manifest.permission.INTERNET,//访问⽹络连接，可能产⽣GPRS流量
Manifest.permission.BLUETOOTH,//允许程序连接到已配对的蓝⽛设备
Manifest.permission.CAMERA,//相机
Manifest.permission.WRITE_SETTINGS,//允许程序读取或写⼊系统设置*/
};
permissionList.clear();
for (int i = 0; i < permissions.length; i++) {
if (ContextCompat.checkSelfPermission(activity, permissions[i]) != PackageManager.PERMISSION_GRANTED) {
Log.e(TAG,"权限未允许："+permissions[i]+"....");
permissionList.add(permissions[i]);
}
}
if (permissionList.isEmpty()) {//未授予的权限为空，表⽰都授予了
Log.e(TAG,"已经获取到了所有权限");
return true;
} else {//请求权限⽅法
String[] spermissions = Array(new String[permissionList.size()]);//将List转为数组
}
return rs;
}
4.处理授权回调
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
alertdialog使用方法if(requestCode==1){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
boolean request_rs=true;
for(int i=0;i<grantResults.length;i++){
if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {
request_rs=false;
}
}
if(request_rs){
Log.e("软件获取权限结果：","获取软件权限成功");
init();
}else{
Toast.makeText(this, "您拒绝了软件应⽤权限，因此⽆法使⽤该软件！", Toast.LENGTH_LONG).show();                    showDialogTipUserGoToAppSettting();
}
}
}
}
若未获取的权限，则提醒⽤户⼿动开启权限
/**
* 提⽰⽤户去应⽤设置界⾯⼿动开启权限
*/
private void showDialogTipUserGoToAppSettting() {
new AlertDialog.Builder(this)
.setTitle("存储权限不可⽤")
.setMessage("请在-应⽤设置-权限-中，允许应⽤使⽤存储权限来保存⽤户数据")
.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();
android.os.Process.killProcess(android.Pid());
}
})
.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
android.os.Process.killProcess(android.Pid());
}
}).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);
}
⼆、调⽤应⽤打开本地⽂件
第⼀种，根据⽂件类型⾃动选取应⽤打开⽂件
1.创建⽂件类型数组
/**
* -- MIME 列表 --
*/
public static final String[][] MIME_MapTable = {
// --{后缀名， MIME类型}  --
