尝试保存图片时,我在Galaxy J5(Android 6.0)中遇到以下错误:
java.io.FileNotFoundException: /storage/FA49-E5D3/DCIM/Camera/20170311_140435.jpg: open failed: EACCES (Permission denied)
我拥有以下权限:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
活动:
if (Build.VERSION.SDK_INT >= 23) {
System.out.println("checking permissions...");
// -------------------------------------- PERMISOS CAMARA -------------------------------------------------
if (checkSelfPermission("android.permission.CAMERA") != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{"android.permission.CAMERA"}, 137);
return;
}
// ---------------------------------- PERMISOS READ EXTERNAL ---------------------------------------------
if (checkSelfPermission("android.permission.READ_EXTERNAL_STORAGE") != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{"android.permission.READ_EXTERNAL_STORAGE"}, 139);
return;
}
// ---------------------------------- PERMISOS WRITE EXTERNAL ---------------------------------------------
if (checkSelfPermission("android.permission.WRITE_EXTERNAL_STORAGE") != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{"android.permission.WRITE_EXTERNAL_STORAGE"}, 138);
return;
}
} else {
System.out.println("API < 23... Skip permissions...");
}
请注意,这在摩托罗拉G3(Android 6.0)中正常运行,可以将图像保存在此路径中:
/storage/emulated/0/DCIM/Camera/IMG_20170311_115623958.jpg
答案 0 :(得分:4)
您正在尝试在micro SD卡上写入文件。但它们现在仅适用于应用程序。只有系统相机应用程序才有权在SD上的DCIM文件夹中写入。
查看getExternalFilesDirs()返回的第二个项目。您的应用可以在SD卡上的特定应用目录中写入。
