因此，我的最新應用運行到這個問題，它在logcat中抱怨說，設備上沒有剩餘空間來保存文件，但這絕對不是這種情況因爲我可以關閉我的應用程序，打開相機並拍照。其他人如何處理這個問題。Android - 如何解決「設備上沒有剩餘空間」錯誤
編輯：此方法
private void writeFile(Bitmap bmp, File f) {
FileOutputStream out = null;
try {
out = new FileOutputStream(f);
bmp.compress(Bitmap.CompressFormat.PNG, 80, out);//<---error here
} catch (NullPointerException e) {
e.printStackTrace();
Log.w("nullpointerException on image error", "nullpointer");
} catch (FileNotFoundException e) {
Log.w("fileNotfoundException on image error", "filenotfound");
// TODO Auto-generated catch block
e.printStackTrace();
}
finally {
try { if (out != null) out.close(); }
catch(Exception ex) {}
}
}
出現的錯誤，這是對這個錯誤的logcat的報告：

編輯：繼承人如何我雖然創建於外部存儲器
目錄這就是我用來創造我認爲是SD卡的地方
String sdState = android.os.Environment.getExternalStorageState();
if (sdState.equals(android.os.Environment.MEDIA_MOUNTED)) {
File sdDir = android.os.Environment.getExternalStorageDirectory();
cacheDir = new File(sdDir,"data/gr");
}
else
cacheDir = context.getExternalCacheDir();
if(!cacheDir.exists())
cacheDir.mkdirs();
if(sdState.equals(android.os.Environment.MEDIA_MOUNTED)){
File adSdDir = android.os.Environment.getExternalStorageDirectory();
adCacheDir = new File(adSdDir,"data/ad");
}else
adCacheDir = context.getExternalCacheDir();
if(!adCacheDir.exists())
adCacheDir.mkdirs();
}
，然後在我尋找或創造的形象進入該目錄的方法：
private Bitmap getBitmap(ImgRequestObj ids) {
String url = null;
String filename = ids.objId.toString();
File f = null;
try{
if(ids.objName.equals("mark")){
url = graffMarksURL;
f = new File(cacheDir, filename);
}else if(ids.objName.equals("admark")){
url = adMarksURL;
f = new File(adCacheDir, filename);
}
// Is the bitmap in our cache?
Bitmap bitmap = BitmapFactory.decodeFile(f.getPath());
if(bitmap != null) return bitmap;
// Nope, have to download it
try {
BitmapFactory.Options bfOptions=new BitmapFactory.Options();
bfOptions.inDither=false; //Disable Dithering mode
bfOptions.inPurgeable=true; //Tell to gc that whether it needs free memory, the Bitmap can be cleared
bfOptions.inInputShareable=true; //Which kind of reference will be used to recover the Bitmap data after being clear, when it will be used in the future
DefaultHttpClient client;
HttpResponse response = null;
HttpParams params = null;// new Http parameters to be used for extra buffering room in VM
HttpPost post = null;
InputStream is = null;
BufferedInputStream bis = null;
Bitmap bmp = null;
ArrayList<NameValuePair> nvp1 = new ArrayList<NameValuePair>();
nvp1.add(new BasicNameValuePair("id", ids.objId.toString()));
// - martin passing id to php script select statement
client = new DefaultHttpClient();
try {
post = new HttpPost(url);
params = post.getParams();//Setting the new Http params to post
post.setEntity(new UrlEncodedFormEntity(nvp1));
try{
HttpConnectionParams.setSocketBufferSize(params, 8192);//Defining the new buffer size
response = client.execute(post);
}
catch(HttpResponseException e){
e.getCause();
}
//Capture response from query and prepare as input
HttpEntity entity = response.getEntity();
// move content to Input Stream
is = entity.getContent();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
bis = new BufferedInputStream(is);
try{
bmp = BitmapFactory.decodeStream(bis, null, bfOptions);
}finally{}
if(is != null)
try {
is.close();
//response = null;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//Log.w("inputstream of image closed", "for this image "+id.toString());
if(bis != null)
try {
//response = null;
bis.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
bitmap = bmp;
writeFile(bitmap, f);
try{
bmp = null;
}catch(NullPointerException e){
e.printStackTrace();
}
return bitmap;}
catch(Exception e){
e.printStackTrace();
}
return bitmap;
}catch(NullPointerException e){
e.printStackTrace();
}
return null;
}
和你如何準備'文件f'？ – waqaslam 2012-02-16 23:06:52
你如何構建文件f的路徑？如果你不小心，你可能會使用內部存儲器，而不會影響平臺相機。 – 2012-02-16 23:09:22
