一，安装代码
private void installUseAS(String filePath) {
File file = new File(filePath);
Uri uri = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Uri contentUri = FileProvider.getUriForFile(mContext, BuildConfig.APPLICATION_ID + ".fileprovider", file);
intent.setDataAndType(contentUri, "application/vnd.android.package-archive");
} else {
intent.setDataAndType(uri, "application/vnd.android.package-archive");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
mContext.startActivity(intent);
}
二，适配7.0代码FileProvider
1，Minifest中配置
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
2，新建file_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="my_images"
path="images/" />
<files-path
name="name"
path="path" />
//相当 Context.getFilesDir() + path, name是分享url的一部分
<cache-path
name="name"
path="path" />
//getCacheDir()
<external-path
name="name"
path="path" />
//Environment.getExternalStorageDirectory()
<external-path
name="download"
path="Download" />
<external-files-path
name="name"
path="path" />//getExternalFilesDir(String) Context.getExternalFilesDir(null)
<external-cache-path
name="name"
path="path" />
//Context.getExternalCacheDir()
</paths>
