- 在我的项目
AndroidManifest.xml增加配置项：
<provider android:name="androidx.core.content.FileProvider" android:authorities="${applicationId}.fileprovider" android:exported="false" android:grantUriPermissions="true" tools:replace="android:authorities"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_provider_paths" tools:replace="android:resource" /></provider>- 在
res/xml目录下增加文件file_provider_paths，内容如下：
<?xml version="1.0" encoding="utf-8"?><paths xmlns:android="http://schemas.android.com/apk/res/android"> <external-files-path name="external_files_path" path="." /> <external-cache-path name="external_cache_path" path="." /> <external-path name="external_path" path="." /> <files-path name="files_path" path="." /> <cache-path name="cache_path" path="." /></paths>这里须要理解了一下Android文件系统。
| XML | 代码 | 文件门路 |
|---|---|---|
| <external-files-path name="external_files_path" path="." /> | Context.getExternalFilesDir(String) | /storage/emulated/0/Android/data/<application package>/files |
| <external-cache-path name="external_cache_path" path="." /> | Context.getExternalCacheDir() | /storage/emulated/0/Android/data/<application package>/cache |
| <external-path name="external_path" path="." /> | Environment.getExternalStorageDirectory() | /storage/emulated/0 |
| <files-path name="files_path" path="." /> | Context.getFilesDir() | /data/data/<application package>/files |
| <cache-path name="cache_path" path="." /> | Context.getCacheDir() | /data/data/<application package>/cache |
