【问题描述】：
我是 android 新手，我正在一个 android 现有项目中工作。该应用程序在 android 版本 >6.0 上崩溃，但有以下异常。基本上应用程序正在从图库中选择照片，这在第一次和第二次都可以正常工作以后应用程序崩溃，出现权限拒绝异常。
java.lang.SecurityException: Permission Denial: 读取 com.google.android.apps.photos.contentprovider.MediaContentProvider 乌里 content://com.google.android.apps.photos.contentprovider/0/1/content%3A%2F%2Fmedia%2Fexternal%2Fimages%2Fmedia%2F1022/ORIGINAL/NONE/256350537 从 pid=7789, uid=10145 需要导出提供程序，或者 grantUriPermission()
我浏览了几个链接并检查了 android 是否引入了运行时权限，并且我使用下面的代码来检查运行时权限。
到目前为止我尝试过的事情......
- 在清单中添加了权限。
2.从代码中检查运行时权限。
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
Log.d("Enter", "onRequestPermissionsResult: ");
switch (requestCode){
case REQUEST_CODE_PERMISSION:{
Map<String,Integer> perms = new HashMap<>();
//Initialize the map with the permissions
perms.put(Manifest.permission.ACCESS_COARSE_LOCATION,PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.CAMERA,PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.READ_EXTERNAL_STORAGE,PackageManager.PERMISSION_GRANTED);
// perms.put(Manifest.permission.READ_USER_DICTIONARY,PackageManager.PERMISSION_GRANTED);
//Fill with actual results from user
if (grantResults.length > 0){
for (int i = 0 ; i < permissions.length ; i++){
perms.put(permissions[i],grantResults[i]);
//check for all permissions
if (perms.get(Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED
&& perms.get(Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED
&& perms.get(Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED){
Log.d("Permission Granted", "onRequestPermissionsResult: ");
}else{
Log.d("Some", "onRequestPermissionsResult: ");
//if (perms.get(Manifest.permission.ACCESS_COARSE_LOCATION))
if (ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.CAMERA)
|| ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.ACCESS_COARSE_LOCATION)
|| ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.READ_EXTERNAL_STORAGE)){
new DialogInterface.OnClickListener(){
@Override
public void onClick (DialogInterface dialog, int which){
switch (which){
case DialogInterface.BUTTON_POSITIVE:
checkAndRequestPermission();
break;
case DialogInterface.BUTTON_NEGATIVE:
break;
}
}
};
}else{
Toast.makeText(this,"Go to Settings and enable Permissions",Toast.LENGTH_LONG).show();
}
}
}
}
}
}
}
private void showDialogOK(String message, DialogInterface.OnClickListener okListener){
new AlertDialog.Builder(this)
.setMessage(message)
.setPositiveButton("OK",okListener)
.setNegativeButton("Cancel",okListener)
.create()
.show();
}
}
而它崩溃的那一行是：-
if (checkAndRequestPermission()){
InputStream fis = getContentResolver().openInputStream(Uri.parse(url)); //Crashing Line
BitmapFactory.decodeStream(fis, null, o);
fis.close();
}
以下是我的清单中使用的权限：
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_USER_DICTIONARY"/>
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.MANAGE_DOCUMENTS"/>
<uses-permission android:name="com.google.android.apps.photos.permission.GOOGLE_PHOTOS"/>
<!-- <uses-permission android:name="com.google.android.apps.photos.permission.GOOGLE_PHOTOS"/>-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<!-- The following two permissions are not required to use
Google Maps Android API v2, but are recommended. -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="com.google.android.apps.photos.permission.GOOGLE_PHOTOS"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-feature android:name="android.hardware.location" android:required="true" />
<uses-feature android:name="android.hardware.location.gps" android:required="false" />

我可以看看你的清单文件吗？？

@jankigadhiya 我在问题中添加了清单权限列表。
